Answer:

4x +$8

Step-by-step explanation:

You know that ...

cost of both orders = cost of first order + cost of second order

Subtracting the cost of the first order gives ...

cost of both orders - cost of first order = cost of second order

(7x +$13) -(3x +$5) = cost of second order

(7x -3x) +($13 -$5) = cost of second order

4x +$8 = cost of second order
