Admission to the zoo costs $3 per person. A family has a coupon for a discount of $5. There are "p" people in the family. Write an expression to represent how much the family pays. *
3p-5
3 p - 15
if and only if p >/= 5
sorry read 15 as 5
3 p - 5
assuming p>1
it wouldn't be much of a family if p=1 ... :-)
LOL, it was more important when I thought the discount was for 15.
To represent how much the family pays, we need to take into account the cost per person and the discount from the coupon.
The cost per person is $3. So, the total cost for "p" people without any discount is 3p.
The coupon offers a discount of $5. Therefore, we need to subtract the discount from the total cost. The expression to represent how much the family pays is:
3p - 5
