Question

Tomas is making trail mix using granola and walnuts. He can spend a total of $12 on the ingredients. He buys 3 pounds of granola that costs $2.00 per pound. The walnuts cost $6 per pound. He uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. He solves the equation for y, the number of pounds of walnuts he can buy.

Answer 1

Answer:

x + 3y ≤ 6

1 pound of walnuts he can buy

Step-by-step explanation:

the number of pounds of granola  = x

granola  costs $2.00 per pound

granola   total cost  = 2x  $

number of pounds of walnuts = y

The walnuts cost $6 per pound

walnuts total cost  = 6y  $

Total Cost = 2x + 6y

spend a total of $12 on the ingredients

=> 2x + 6y ≤ 12

=> x + 3y ≤ 6

x = 3

=> 3 + 3y ≤ 6

=> 3y ≤ 3

=> y ≤ 1

=>  the number of pounds of walnuts he can buy = 1
