Answer 1

The amount of money Monica earns if each cheesecake was cut into 12 slices = $263.9

Explanation:

The amount of money Monica earns by selling cheesecake is represented by the following variable expression:

`2.9(7s+7)`

where
`s` represents the number of slices of cheesecake.

To find the money Monica would earn if each cheesecake was cut into 12 slices.

Solution:

In order to find the total amount earned by Monica if the number of slices the cheesecake is cut into is 12, we will plugin 12 for variable
`s` in the given expression.

The expression :

`2.9(7s+7)`

Plugging in
`s=12`

⇒
`2.9(7(12)+7)`

Simplifying and evaluating.

⇒
`2.9(84+7)`

⇒
`2.9(91)`

⇒
`263.9`

Thus, she earns = $263.9
