Step-by-step explanation:
10^2 = 100
10^-2 = 1/100 ➡ 0.01
For this case we have the following situation:
The monthly cost of a gym in the city is $ 3. The initial registration is $ 25. Write a mathematical expression that models the problem.
So we have to define variables:
x: number of months
y: total cost
The mathematical expression that models the problem is:
89.95 x 0.05 (5%)
=4.4975
The final cost of the DVD player is 89.95-4.4975
=85.4525
≈ $85.45
