Tony had 20$ he wants to buy at least 4 snacks. Hot dogs (x) are 3$ each peanuts (y) are 2$ each

Question

So what would be the total price? I have never done this one before.

Total snacks: X + Y > (greater than or equal to) 4

Total price: 3x + 2y < (less than or equal to) [?]

Answer 1

x+y>/=4

3x+2y</=20

if he buys 10 peanuts, total price =2(10)=$20

if he buys 4 peanuts, total price = 2(4) = $8

$8</= total price </= $20

x, y total price
