A) You have $50 and plan to buy movie tickets for $8. How much money, y, will you have left after buying x tickets?

Step-by-step explanation:

Given:

Equation is y = - 8x + 50

we need to find which problem statement represents the above equation.

Hence we will check it by creating equation for each.

A) You have $50 and plan to buy movie tickets for $8. How much money, y, will you have left after buying x tickets?

Cost of movie ticket = $8

Number of tickets = x

Money i have = $50

Money left y = 50 - 8x

Hence we can say that this problem represent the above equation.

B) Over the summer, you and 8 friends plan to read 50 books. If everyone gets an equal amount, how many books, y, will each person read?

Total friends = 9

Number of books = 50

Number of books each will read = 50/9

Hence we can say that this problem does not represent the above equation.

C) You have already traveled 50 miles. How far, y, will you travel in 8 hours, at a speed of x miles per hour?

Number of hours = 8

Number of miles = x

Miles traveled = $50

Distance traveled = 50 + 8x

Hence we can say that this problem does not represent the above equation.

D) You start with $50 in your savings account. How much money, y, will you have after saving $8 a month for x months?

Amount per month = 8

Number of months = x

Money in savings account = $50

total Money saved = 50 + 8x

Hence we can say that this problem does not represent the above equation.

Final Answer:

Option A will be correct option which represent the equation y = - 8x + 50
