Question

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

Answer 1

Let us assume total cost of the TV is = $x

Sarah pays a 20%.

So, the remaining % would be 100-20 = 80%.

Therefore, we can say that Sarah pays extra $96 is the 80% of x.

Let us repharse the problem now.

"80% of x is 96".

So, we can setup an equation.

80% of x = 96.

80% in decimal form can be written as 80/100 = 0.80.

Therefore, 0.80x = 96.

Dividing both sides by 0.80, we get

x = $\frac{96}{0.80}$

x=120.

Therefore, total cost is $120.
