Using this table, calculate the profit at each level of running shoe inserts production. pair 1: $ pair 2: $ pair 3: $ pair 4: $ pair 5: $

1 pair = 23

2 pair = 51

3 pair - 80

4 pair - 109

5 pair = 137

Step-by-step explanation:

Profit = Total revenue - total cost

If we make 1 pair of running shoe inserts

 Profit = 30-7 =23

If we make 2 pairs of running shoe inserts

 Profit = 60-9 =51

If we make 3 pairs of running shoe inserts

 Profit = 90-10 =80

If we make 4 pairs of running shoe inserts

 Profit = 120-11 =109

If we make 5 pairs of running shoe inserts

 Profit = 150-13 =137

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

answer is because 4×10=40

and 98×4= is 392

40,392
