Answer:

Sandy had $87 before buying the pie.

Step-by-step explanation:

x = $80 (Current amount of money)

y = $7 (How much she spent on pie)

z = How much money she had before buying the pie.

x + y = z

$80 + $7 = z

$80 + $7 = $87

Sandy had $87 before buying the pie.

Anyone know how to do this?

Lera25 [3.4K]

Answer:

Part A) 25

Part B) 225

Step-by-step explanation:

Part A

The slope of the graph gives us the mile per gallon of the car.

Recall that the slope of the graph is rise over run.

$m = \frac{200}{8} = 25$

Therefore car gets 25 miles per gallon

Part B) Since we know the slope of the direct variation line, we substitute into y=kx to get:

$y = 25x$

To find the number of miles the car travels using 9 gallons, we substitute x=9 to get:

$y = 25 \times 9$

This gives us 225 miles
