150 - 8d = 175 - 10d
-8d + 10d = 175 - 150
2d = 25
d = 25/2
d = 12.5...so each dvd costs 12.50

150 - 8(12.5) = 150 - 100 = 50
175 - 10(12.5) = 175 - 125 = 50

so they will each have 50 bucks left on their card

Erica sells bracelets for $2 each. The supplies to make each bracelet costs her $0.75. Let “n” represent the number of bracelet
AysviL [449]

Answer:  1.25n

=======================================================

Explanation:

Erica sells bracelets for $2 each. If she makes and sells n of them, then she gets 2n dollars of revenue.

Making n bracelets cost her a total of 0.75n dollars because each bracelet costs 0.75 dollars, or 75 cents.

Subtract the revenue and cost to get the profit

profit = revenue - cost

profit = 2n - 0.75n

profit = (2-0.75)n

profit = 1.25n

The expression 1.25n means that she earns $1.25 in profit per bracelet sold.
