• At store A, 3 pounds of apples cost $12.
• At store B, the cost is given by y = 2x where y is the cost in dollars and x is the number of pounds of apples.
• The cost of apples at store C is shown in the graph.
(don't worry about the graph I know how to do this one)
Answer the questions to find out which store's apples are the least expensive.
2. What is the unit price of apples at store B? How did you use the equation to find the unit price? (2 points)
Answer:
The unit price is the cost per unit of an item or the cost/price for each item.
1) 4$ per pound. By simplifying the proportion (constant ratio) between the cost, and the pounds of apples. 3 pounds of apples cost 12$ → 3/3 pounds of apples cost 12/3$ → 4 dollars for every pound.
2) 2$ per pound. By evaluating the rate of change (change in the y over x or dependent variable over independent) in the equation: y = 2x. y is the cost in dollars, and x is the pounds of apples. So there are 2 pounds (weight) of apples for every dollar.
3) 3$ per pound. Given a graph with a y scaled by 3, and an x scaled by 1 with a graph y = x or 1 unit up for every unit right. This must be equivalent to y = 3x. Where y is labeled as the cost in dollars, and x as the weight in pounds. So there are 3 dollars for every pound of apples.
4) Store B. Because 2 is less than 3 which is less than 4.

a big bag contains 500 beads, each of the same size, but in 5 different colors. Suppose there are 100 beads of each color and I am blindfolded. What is the fewest number of beads I must pick to be absolutely sure there are 5 beads of the same color among the beads I have picked blindfolded?
I WILL REPORT ANY FAKE OR USELESS ANSWERS
Answer:
I believe the answer is (4 * 5 +1) = 21
Step-by-step explanation:
The fewest number of beads you must pick to be absolutely sure there are 5 beads of the same color is 20 + 5 = 25 beads.
How to determine the fewest number of beads I must pick to be absolutely sure there are 5 beads of the same colorTo guarantee that you have picked 5 beads of the same color, you need to ensure that you have at least 4 beads from each of the 5 colors.
To calculate the fewest number of beads you must pick, we can consider the worst-case scenario where you have picked the maximum number of beads from each color without having 5 of the same color.
In this scenario, you would have 4 beads from each color, which totals 4 * 5 = 20 beads.
However, to guarantee that you have 5 beads of the same color, you need to pick one more bead from each color, which is an additional 5 beads.
Therefore, the fewest number of beads you must pick to be absolutely sure there are 5 beads of the same color is 20 + 5 = 25 beads.

Mrs.Rose received a 35% discount on her cell phone. The price of her cell phone came out to be $180. How much was the original price of her cell phone?
Answer:
The original price of the cell phone is $514.29
Step-by-step explanation:
The answer is $514.29 because the equation to find the answer is :
Let x = the original price of the cell phone
$180 = Price after discount
So, 180 = x * 35/100
Multiply by its reciprocal on both sides so
180 (100/35) = x
18000/35 = x
514.29 = x
So the original price of the cell phone is $514.29
