Question

A weightlifter can increase the weight W(x) that she can lift according to W(x) = 315(1.05)", where x represents the number of training cycles completed. How much will she

lift after 4 training cycles?

Answer 1

She will lift 383 units.

Explanation:

The amount of weight that she can lift after x cycles is given by:

`W(x) = 315(1.05)^x`

How much will she lift after 4 training cycles?

This is W when x = 4, that is, W(4). So

`W(x) = 315(1.05)^4 = 383`

She will lift 383 units.
