A local fish market is selling fish and lobsters by the pound. The fish, f, costs $5.00 a pound, while the lobster, l, costs $8.00 a pound. The fish market sells 20.5 pounds and makes $131.00. How many pounds of fish and pounds of lobster did the market sell?
Given :
A local fish market is selling fish and lobsters by the pound. The fish, f, costs $5.00 a pound, while the lobster, l, costs $8.00 a pound. The fish market sells 20.5 pounds and makes $131.00.
To Find :
How many pounds of fish and pounds of lobster did the market sell.
Solution :
Let, pounds of fish sells are x.
So, pounds of lobsters sells are (20.5 - x) .
Total amount of spend = 5x + 8( 20.5 - x)
5x + 8( 20.5 - x) = 131
5x - 8x + 164 = 131
3x = 33
x = 11
Therefore, number of pounds of fish and lobsters are 11 and 9.5 pounds respectively.
Hence, this is the required solution.

The total cost of Anja’s trip to the dentist was $628.35. She paid a flat fee of $89.95 which included the checkup and cleaning and then had 4 cavities filled, each of which cost the same amount. Which shows the correct equation and value of x, the cost of each cavity filling?
A. 4 x + 89.95 = 628.35; x = 134 dollars and 60 cents
B. 4 (89.95) + x = 628.35; x = 268 dollars and 55 cents
C. 4 x + 89.95 = 628.35; x = 179 dollars and 58 cents
D. 4 (89.95) + x = 628.35; x = 538 dollars and 40 cents
Answer:
A
Step-by-step explanation:

A person invests 9500 dollars in a bank. The bank pays 5% interest compounded annually. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 13200 dollars?
Answer:
6.58 years
Step-by-step explanation:
Step one:
Given data
Principal=$9500
rate= 5%= 0.05
Final amount= $13200
Required:
The time t
Step two
The expression for the compound interest is
[tex]A= p(1+r)^t[/tex]
t = ln(A/P) / r.
substitute
t = ln(13200/9500) /0.05
t= ln(1.39)/0.05
t=0.329/0.05
t=6.58 years

^2 = SQUARED( to the second power)
Answer:
2. 2x times 2x equals 4x^2 since x times x equals x^2(and 2 times 2 equals 4. then positive i times negative i equals -i^2 which can transfer to be 1.
Step-by-step explanation:
2. 2x * 2x = 4x^2
+i * -i = -i^2
-i^2 can be transferred into positive 1.
i is a variable. if you divide -i^2 by -i, then that equals i, which is 1.
3. The same thing as 2.^
1 squared is 1. i squared is i^2. i^2 divided by i is i. i is 1. 1+1 is 2. Now put the 2 infront of the i to make 2i.

A coin collection consists of dimes and nickels. If there are a total of 500 coins valued
at $39. how many dimes are there?
Answer:
There are 280 dimes
Step-by-step explanation:
A nickel is worth 5 cents while a dime is worth 10 cents
Let n be number of nickel
d the number of dimes
n + d = 39
Secondly
$39 is same as 3900 cents
So we have;
10d + 5n = 3900
From first equation;
n = 500-d
Put this in second equation;
10d + 5(500-d) = 3900
10d + 2500-5d = 3900
5d = 3900-2500
5d = 1400
d = 1400/5
d = 280
