Answer:
-13 + 5*n-1 I think
Step-by-step explanation:
Cost/(number of cassettes) = $14.50/2 = x/15
Multiply by 15 to solve
15*($14.50/2) = x = $108.75
15 cassettes will cost $108.75.
We need to substituter the values for the variables. 2(8)(2)/(6), or 32/6, or 5.3333
Rounding to the nearest cent the answer is 1 i believe
