Answer:

Marge has earned $60.

Step-by-step explanation:

Let the total money she earned be x.

Money spent o the phone = $\frac{1}{2}x=0.5x$

Money left with Marge after buying phone= x - 0.5 x = 0.5 x

Money spent on the gift= $\frac{0.5x}{2}=0.25x$

Money left with Marge after buying gift= 0.5 x - 0.25 x = 0.25x

Final amount left with marge = $15

$\$15=0.25x$

$x=\frac{\$15}{0.25}=\$60$

Marge has earned $60.

1 gallon / 200 ft^2 = x gallons / 885ft^2

cross multiply (200 • x, 1 • 885)

200x = 885

x = 4.425 gallons
