Maria paid $.80 for some packages of cards she sold all but 18 packages for two dollars each making a profit of $48 how many packages of cars does she buy?

Maria bought 70 packages

Step-by-step explanation:

Maria bought n packages of cards at $0.80 per package.

She sold n - 18 packages at $2.

She made a profit of $48.

Profit = (Amount of money made selling packages) - (Amount of money spent buying packages)

Profit = $48 = ($2)(n - 18) - ($0.80)n

2(n - 18) - 0.80n = 48

2n - 36 - 0.80n = 48

1.2n - 36 = 48

1.2n = 84

n = 70

Maria bought 70 packages

answer: 1,380
