mark brought 14 tapes, some priced at $6 each and the rest priced at $8 each. if he spent $94 altogether, how many tapes did he buy at each price?

Answer 1

Let x be the number of tapes priced at $6 each and y be the number of tapes priced at $8 each.

We can set up a system of equations based on the given information:

x + y = 14 (total number of tapes)
6x + 8y = 94 (total cost of tapes)

Solving the system of equations, we get:
6x + 6y = 84
6y = 10
y = 10/6
y = 5

Substitute y back into the first equation:
x + 5 = 14
x = 14 - 5
x = 9

So, Mark bought 9 tapes priced at $6 each and 5 tapes priced at $8 each.
