Question

Sarah pays a 20% deposit for a new TV and then an extra $96. What’s the total cost?

Answer 1

A deposit (in this case) is a portion of the TV paid in advance - 20% of the total cost. That means that the 96$ makes up the remaining 80% of the total cost, which I'll represent as x. From here, we can set up an equation to find the total cost x, since we have a relation to form it on - the fact that 80% of x is equal to 96$.

`0.8x = 96`

`(0.8x)/(0.8) = (96)/(0.8)`

`x = 120`

The total cost of the TV is 120 dollars.
