Answer:
She will lift 383 units.
Step-by-step explanation:
The amount of weight that she can lift after x cycles is given by:
[tex]W(x) = 315(1.05)^x[/tex]
How much will she lift after 4 training cycles?
This is W when x = 4, that is, W(4). So
[tex]W(x) = 315(1.05)^4 = 383[/tex]
She will lift 383 units.
