Answer:

(3, 1.5)

Step-by-step explanation:

Given the system:

6x + 8y = 30
y=1/2x

Substitute y and solve for x:

6x + 8y = 30
6x + 8(1/2x) = 30
6x + 4x = 30
10x = 30
x = 3

Find y:

y = 1/2x
y = 1/2(3)
y = 1.5

Solution is (3, 1.5)

timofeeve [1]

Mickey incorrectly calculated the unit price:
$\frac{12}{22.20} = 0.54$

The correct operation is:
$\frac{22.20}{12} = 1.85$

Each carton costs 1.85, so 7 cartons cost
$1.85 \times 7 = 12.95$
