Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12.
Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct?

Answer:

Ariana is correct. The difference in the price is $3. So the percentage that you saved has to equal $3.

Step-by-step explanation:

$15.00 x .10 or 10% = $1.50

$1.50 x 2 will give you 20%

$1.50 x 2 = $3.00

$15.00-$3.00 = $12.00

Answer:

Haley is the correct answer

Jerry started doing sit-ups every day. On the first day, he did 18 sit-ups. Every day after that he did 4 more sit-ups than he had done the previous day. Today Jerry did 26 sit-ups. Enter an equation that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day.

The equation __ d + __= __can help find the number of days Jerry has been doing sit-ups.
