Question

Ryan bought grapes last week for $1.65 per pound. If he bought n pounds, write an equation to show how much money (m) he will spend.

Answer 1

N = # pounds
$1.65 = price per pound
grapes cost $\frac{1.65}{pound}$
When you multiply cost/pound by the number of pounds, the result is the cost for however much of the grapes Ryan buys.

Therefore,
m = 1.65n
