Question

HELP!!!!!!!!!
Tony has $60 to buy sovenirs for his grandkids at the baseball game pennants cost $7.50 and hats cost $11.99 This relationship can be represented by the inequality 7.5p+11.99h≤60 Three of tony's kids wants hats. Which inequality represents how many pennants he can buy?

A. p≤3.204
B. 0≤P≤3
C. P≤3
D. 0≤P≤3.204

Answer 1

ok so if 3 of the kids want hats, you are doing
7.5p+11.99(3) is less than or equal to 60
You have to replace h with 3 bc u r buying 3 hats. If you solve that, you have
7.5p+35.97 is less than or equal to 60
Then you solve it like an equation. So u subtract 35.97 from each side to get
7.5p is less than or equal to 24.03
Then you solve for p by dividing by 7.5 on each side to be
p is less than or equal to 3.204
However, you can't buy .204 of a pennant, so u have to round it down to 3. So u have
p is less than or equal to 3
But from that equation, p can be -100, bc its less that 3, but it really can't bc u can't have negative amount of items.
So u would have to change the equation to 0<=P<=3

Answer 2

so the answer is B
