Charity and Sabria both are nail artists. Charity charges $75 for a set of nails with designs and Sabria charges $70 for the same type set of nails. This week Charity made an additional $65 in tips and Sabria made an additional $95 in tips. Given that C and S represent the number of sets of nails completed by Charity (C) and Sabria (S), which expression can be used to represent their combined earnings for the week.(1 point)

145CS + 160

145(C + S) + 160

75C + 70S + 160

65C + 70S + 160

The correct expression to represent their combined earnings for the week is: 75C + 70S + 160.

To represent Charity's earnings for the week, the expression is 75C + 65 (1 point)

To represent Sabria's earnings for the week, the expression is 70S + 95 (1 point)

To find the combined earnings for the week, we add the two expressions together:

75C + 65 + 70S + 95

Simplifying, we can combine like terms:

75C + 70S + 160

Therefore, the expression that can be used to represent their combined earnings for the week is 75C + 70S + 160, which is option (3).

To find the expression representing their combined earnings for the week, we need to consider the base charges for Charity and Sabria's sets of nails, as well as the additional tips they both received.

Charity charges $75 for a set of nails with designs, and she made an additional $65 in tips. Therefore, her earnings for the week can be represented by the expression 75C + 65.

Similarly, Sabria charges $70 for the same type of set of nails and made an additional $95 in tips. Thus, her earnings for the week can be represented by the expression 70S + 95.

To find their combined earnings, we add both expressions together:

75C + 65 + 70S + 95

Simplifying this expression gives:

75C + 70S + 160

Therefore, the expression that represents the combined earnings for Charity and Sabria for the week is:

75C + 70S + 160.
