Rich bought 5 cupcakes and one pie. He know his total bill and know the pie was 6.88, but he wants to find the price if the cupcakes. How can he determine the price of each cupcake?

if there is no tax he can subtract 6.88 from the total bill and then divide the answer by 5 or use the following equation:

where t = total bill and c = cupcake

the correct is answer is a 9-sided polygon!

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
