The choice D.

$V = \frac{M - 6}{3}$

Step-by-step explanation:

$M = 3V + 6 \\ 3V = M - 6 \\ \\ V = (M - 6) \div 3 \\ \\ V = (M - 6) \times \frac{1}{3} \\ \\ V = \frac{M - 6}{3}$

I hope I helped you^_^

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

ATQ

24+17.95x = 18+18.95x

24-18=18.95x-17.95x

24-18=x

6=x

Hence they need to buy 6 pairs of uniform pants so that they pay the same amount for their purchases
