The correct expression to represent their combined earnings for the week is 75C + 70S + 160.
The expression that can be used to represent their combined earnings for the week is:
75C + 70S + 160
To find the expression that represents the combined earnings for the week, we can start by considering the base prices for Charity and Sabria's services. Charity charges $75 for a set of nails with designs, and Sabria charges $70 for the same type of set.
Next, we need to account for the additional earnings they made in tips. Charity made an additional $65 in tips, while Sabria made an additional $95 in tips.
To calculate the combined earnings, we can multiply the number of sets of nails completed by Charity (C) by the base price of Charity's service ($75), and multiply the number of sets of nails completed by Sabria (S) by the base price of Sabria's service ($70).
Therefore, the expression that represents their combined earnings is: 75C + 70S
Finally, we need to add the additional earnings in tips to the expression. So, the final expression that represents their combined earnings is: 75C + 70S + (65 + 95) = 75C + 70S + 160
Thus, the correct expression is: 75C + 70S + 160.
