Question

Lorenzo buys 3 shirts at s dollars apiece and 2 pairs of pants at p dollars a pair. What does the expression 3s+2p represents?

Answer 1

The number of shirts Lorenzo buys times how much they cost plus the number of pairs of pants he buys time how much they cost. 

Answer 2

Let

s--------> the cost in dollars of a piece of shirt

p-------->  the cost in dollars of a pair of pant

T-------->  total cost of Lorenzo's buy in dollars

we know that

$T=3s+2p$

therefore

the answer is

the expression represents the total cost of Lorenzo's buy in dollars (the total cost of the 3 shirts and the 2 pairs of pants)
