Summative 1 on standard 7.EE.3: Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically.
Use this scenario to answer questions 3-6:
A store pays two fees when a customer uses a credit card to make a purchase. These fees include
a flat fee of $0.15, and
a processing fee equal to 1.75% of the dollar amount of the purchase.
There is no sales tax on the purchase.
Refer to the scenario above.
Estimate the approximate amount of fees the store would have to pay when a customer uses a credit card for a $60.20 purchase. Show or explain how you arrived at your estimate in the space below.
Refer to the scenario above.
Calculate the exact amount of fees, in dollars and cents, the store pays in fees for a $60.20 credit card purchase. Show your work.
Refer to the scenario above.
Compare your answer in #2 to your estimate in #1 and assess the reasonableness of your estimate. Explain if your estimate was accurate or not and why.
Refer to the scenario above.
The store gives a discount to customers who use cash instead of a credit card for a purchase. The discount is equal to ⅘ of the 1.75% processing fee the store would be charged if a credit card was used. A customer is going to make a $150 purchase using cash. What will be the discount, in dollars and cents, for using cash instead of a credit card on this purchase?

Summative 2 on standard 7.EE.4a: Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers.
Circle the equation that best represents the situation.
An adult and 5 children rent skates. It costs $4 per adult for skates and a total of $16.
Circle the equation that best represents the situation.
It costs Mikael $4 to make a bike bag, and he sells each for $5. He has made a profit of $16 so far.
Circle the equation that best represents the situation.
It was 16℃. The temperature began falling 4℃ per hour until it reached 5℃.
Hope made 3 different yo-yos. She used 1 ¾ meters of string to the first yo-yo, 1 meter of string for the second yo-yo, and a total of 4 ⅓ meters of string.
Hope uses the equation 1 ¾ + 1 + y = 4 ⅓ to represent the situation.
What does the variable y represent in the equation?
Raymond just got done jumping at Super Bounce Trampoline Center. The total cost of his session was $43.25. He had to pay a $7 entrance fee and $1.25 for every minute he was on the trampoline.
Write an equation to determine the number of minutes (t) that Raymond was on the trampoline.
Use your equation from #9 to find the number of minutes Raymond was on the trampoline.
