Answer:Benjamin’s age = 30 and David’s age = 6
Explanation:
Let x be the age of Benjamin
Let y be the age of David
x + y = 36
And 2x + 2y = 72
If we plug 30 for x and 6 for y we get:
30 + 6 = 36
36 = 36
2(30) + 2(6) = 72
60 + 12 = 72
72 = 72
=
Answer: x = 2

Answer:
x + y ≥ 20
3x + 5y > 60
Step-by-step explanation:
Let
Bags of candy corn = x
Bags of chocolate = y
Cost of bags of candy corn = $3
Cost of bags of chocolate = $5
He needs to buy at least 20 bags of candy and he cannot spend more than $60
system of linear inequalities to model the situation.
x + y ≥ 20
3x + 5y > 60
The system ot inequalities which models the situation
x + y ≥ 20
3x + 5y > 60
