Question

A new eye clinic sold 47 pairs of eyeglasses the 1st month it was open. Thenumber of pairs of eyeglasses sold increases by 25% each month thereafter.The equation f(x) = 47(1.25)*1 gives the number of pairs of eyeglasses soldeach month after the clinic's opening.About how many pairs of eyeglasses will be sold in the 10th month?

Answer 1

We have that the function that describes the number of eyeglasses sold is :

`f(x)=47\cdot(1.25)^x`

after 10 months, we have that the glasses sold are

`f(10)=47\cdot1.25^(10)\approx438`
