This can be solve by establishing equations.

y be the miles mr storey drovee

the first equation is
y = 3x

second equation
x + y = 3200
then substitute equation 1

x + 3x = 3200
4x = 3200
x = 800 miles mrs storey drove
y = 3x = 2400 miles mr storey drove

Arturiano [62]

Answer:

Step-by-step explanation:

For 11 1/2 gallons, he paid $36.80.

We need to find the cost per gallon.

First, converting 11 1/2 gallons to decimal, it is:

1/2 = 0.5

So, 11 1/2 is 11.5 gallons

So, Cost Per Gallon (last week) = $\frac{36.80}{11.5}=3.2$

There is 5% increase on this $3.20 per gallon. We find 5% of 3.2 and add it to 3.2 to find this week's cost per gallon.

5% = 5/100 = 0.05

0.05 * 3.20 = 0.16

So,

3.20 + 0.16 = $3.36 per gallon

Cost Per Gallon (this week) = $3.36

To buy 9 1/4 gallons it would take:

$3.36*9.25=31.08$

Note: 1/4 = 0.25, so 9 1/4 = 9.25

It would cost $31.08 to buy 9.25 gallons this week

Correct answer is B
