Question

PLEASE HELP ME WILL FAN AND MEDAL!

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

Answer 1

any guesses?

Answer 2

i'm really lost on this and i've tried really hard to understand but i can't ): @satellite73

Answer 3

i would have said \(1.07x=45\) but then wrote it as \(x+.07x=45\)
i wonder why?

Answer 4

if the price is \(x\) dollars, then 7% of it is \(.07x\) and so the total you would pay would be
\[x+.07x\]

Answer 5

since that total has to be no more than $45, you can set
\[x+.07x=45\] and solve for \(x\)

Answer 6

A? @satellite73

Answer 7

The last option is correct. He has 45 dollars, but that has to cover both the cost of the item AND the tax. Since we don't know the cost of the item, we can make that a variable, x. Then we have to find the tax added which is 7% or .07. All of this must equal 45 for him to be able to make the purchase. Thus, x(amount)+x.07(tax added)=45

Answer 8

Hope that helps!

Answer 9

@JoyLin Oh ok. I was reading it wrong, but I get it now. Thanks so much! (:

Answer 10

@JoyLin @satellite73 Do you mind helping me out with 2 more questions?

Answer 11

Yea totally! Ask away! :)

Answer 12

Solve for x: 4 over 5 x + 4 over 3 = 2x

x = __________________ Write your answer as a fraction in simplest form. Use the "/" symbol for the fraction bar.

Answer 14

You're wording it a little oddly. xD
