Eddie has saved up $45 to purchase a new camera from the local store. The sales tax in his county is 7% of the sticker price. Write an equation and solve it to determine the value of the highest priced camera Eddie can purchase with his $45, including the sales tax. Round your answer to the nearest penny.

x - 0.07x = 45; $48.39

0.7x = 45; x = $64.29

7x = 45; x = $6.43

x + 0.07x = 45; x = $42.06

What don't you understand?

i don't understand how to find the answer.

anonymous · Answer

Well, judging from your possible answers, you want to set x=the price of the camera. We know that 7% of x is equal to the sales tax, and the sales tax plus the price of the camera must be under $45

Do you know how to convert a percentage into a decimal?

kidthatbro8 · Answer

yes. so it would either be A or D, right? because they both have the decimal for 7%...?

anonymous · Answer

Thinking about it logically, would it be A or D? We know that the price for the sales tax must be added to the price of the camera...

kidthatbro8 · Answer
