Question

Ivan exercises every day. The function E=10m+6 represents the number of pull-ups he can do in m minutes. After drinking a new sports drink to stay hydrated, he finds that he can increase the number of pull-ups per minute by a factor of 2, represented by the function S=2E. Which function represents the number of pull-ups he can do after drinking the sports dri

Answer 1

`S=20m+12`

Explanation:

We have been given that the function
`E=10m+6` represents the number of pull-ups he can do in m minutes.

After drinking a new sports drink to stay hydrated, the number of pull-ups per minute by a factor of 2, represented by the function
`S=2E`.

To find the function representing the number of pull-ups he can do after drinking the sports drink, we will substitute E's value in our second function.

`S=2(10m+6)`

Upon using distributive property we will get,

`S=20m+12`

Therefore, the function
`S=20m+12` represents the number of pull-ups Ivan can do after drinking the sports drink.
