Question

a electronic store sells a certain digital camera for $126. this is 2/3 of the price that a photography store charges. what is the cost of the camera at the photography store?

Answer 1

Let us assume the cost of the camera at the photography store = $x.

We are given $126 is 2/3 of the price that a photography store charges.

Let us repharse above statement "$126 is 2/3 of the store price x".

Let us convert above statement in an equation now.

126 = 2/3 of x.

126 = 2/3 x.

Dividing both sides by 2/3, we get

126 ÷ 2/3 =2/3 x ÷ 2/3.

126 × 3/2 = x

378/2 =x.

x= 189.

Therefore, the cost of the camera at the photography store is $189.
