Question

Lola fills her car up each week before going to school. She uses the formula y = 28x to determine y, the number of miles she can drive in x gallons. She forgets to refuel her tank one day but now has 3-6 gallons left. What is the range?

a) 84-168 miles
b) 84-196 miles
c) 84-224 miles

Answer 1

Lola can drive between 84-168 miles with 3-6 gallons of gasoline left.

Step-by-step explanation:

The formula y = 28x represents the number of miles Lola can drive in x gallons of gasoline. To find the range of miles she can drive with 3-6 gallons left, we substitute the values into the formula. For 3 gallons, y = 28 * 3 = 84 miles. And for 6 gallons, y = 28 * 6 = 168 miles. Therefore, the range is between 84-168 miles.
