Question

Chris buys p pairs of pants and 4 more shirts than pairs of pants. Shirts cost $18 each and pair of pants cost $25 each. What does each term in the expression 25p + 18 (p+4) represent? What does the entire expression represent?

Answer 1

25p represents the total cost of the pants.
18(p+4) represents the total cost of the shirts.

The entire expression represents the total amount of money spent.

I'm not sure if this is right. 
Hope it helps though. :) 

Answer 2

Answer with Step-by-step explanation:

Chris buys p pairs of pants and 4 more shirts than pairs of pants.

i.e. Chris buys number of shirts= p+4

Shirts cost $18 each

Cost of (p+4) shirts=18(p+4) dollars

Pair of pants cost $25 each.

Cost of p pair of pants= 25p dollars

Total cost of shirts and pants Chris buys= 25p+ 18(p+4)

Hence, 25p means Cost of p pair of pants or cost of number of pants Chris buys

18(p+4) means Cost of (p+4) shirts or cost of number of shirts Chris buys

and 25p+ 18(p+4) total cost of shirts and pants Chris buys
