A store is selling pants for 8.99 and shirts for 3.99. You can spend no more then $60 and want to buy at least two pairs of pants which of the following is a solution to the system of inequality

Question

The answers are 2 pants and 12 shirts, 1 pants and 5 shirts, 9 pants and 4 shirts,3 pants and 3 shirts

Answer 1

It simplifies things if you just round off pants price to $9 and shirts to $4

then try each of the 4 answers

2P + 12S = 18+48 = 66 > 60, which is over budget

1P+5S = 9 +20 =29<60, which is feasible, under budget

9P +4S = 81+16 = 97 which is way over budget

3P +3S = 27+12 = 39<60 under budget

1 pants and 5 shirts is possible where you have $31 left over

3 pants and 3 shirts is possible where you have $21 left over

both are solutions to the inequalities
