Answer:
They need to buy 6 pairs of uniform pants so that they pay the same amount for their purchases
Step-by-step explanation:
Let x be the no. of pairs of uniform pants for which the total cost in both the cases will be same.
Case 1:
Cost of 1 pairs of uniform pants = $17.95 each
Cost of x pairs of uniform pants = $17.95x
Cost of sweater = $24.
Total cost = 24+17.95x
Case 2:
Cost of 1 pairs of uniform pants = $18.95
Cost of x pairs of uniform pants = $18.95x
Cost of sweater = $18
Total cost = 18+18.95x
