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?
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.
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)
