a.) 15.1 gallons

c.) 60.4 gallons

b.) 90.6 gallons

d.) 105.7gallons

Answer 1

Answer:

d) $105.7\ \text{gallons}$

Step-by-step explanation:

$150\ \text{miles}$ requires $45.3\ \text{gallons of fuel}$

$1\ \text{mile}$ requires $\dfrac{45.3}{150}\ \text{gallons of fuel}$

$200\ \text{miles}$ requires $200\times \dfrac{45.3}{150}=60.4\ \text{gallons of fuel}$

So, total amount of gasoline required for the trip is $60.4+45.3=105.7\ \text{gallons}$.
