Given that C and S represent the number of sets of nails completed by chery (c) and sabby (s), which expression can be used to represent their combined earnings for the week. (1 point)

A: 145CS + 160
B: 145(C + S) + 160
C: 75C + 70S + 160
D: 65C + 70S + 160

The correct expression to represent their combined earnings for the week is:

C: 75C + 70S + 160

The expression that can be used to represent their combined earnings for the week is:

C: 75C + 70S + 160

Explanation:
- Cherry charges $75 for each set of nails and has completed C sets, so her earnings from the nail sets would be 75C ($75 multiplied by the number of sets).
- Sabby charges $70 for each set of nails and has completed S sets, so her earnings from the nail sets would be 70S ($70 multiplied by the number of sets).
- Both artists also made additional money from tips, $65 for Cherry and $95 for Sabby.
- Finally, they both earned a fixed amount of $160 for the week.
- Therefore, their combined earnings can be calculated by adding the earnings from the nail sets, tips, and the fixed amount: 75C + 70S + 65 + 95 + 160 = 75C + 70S + 320.

So, the expression that represents their combined earnings for the week is:

C: 75C + 70S + 160

To determine the correct expression that represents the combined earnings of Chery and Sabby for the week, let's analyze the information given:

Chery charges $75 for a set of nails with designs and made an additional $65 in tips.
Sabby charges $70 for a set of nails with designs and made an additional $95 in tips.
