Question

Gene has a gasoline budget of $300 per month. He uses an average of $7 of gasoline each day he drives. Which of the following equations represents how much money is left in his gasoline budget after x days of driving? A. y = 300 + 7x B. y = 7x - 300 C. y = 300x - 7 D. y = 300 - 7x

Answer 1

y=300-7x

Explanation:

since monthly budget for gasoline=$300

Per day, he uses an average of $7 of gasoline

after x days he will use $7x of gasoline.

remaining amount after x days of driving= 300-7x

the equation will be y= 300-7x
