Bryan sells cars. He makes a salary of $500 a week, plus $150 for every car he sells. This week, he wants to make at least $2000. How many cars does he need to sell? Write an equation and solve.
Responses
A 150 + 500x ≤ 2000. He needs to sell at least 4 cars.150 + 500x ≤ 2000. He needs to sell at least 4 cars.
B 150 + 500x ≥ 2000. He needs to sell at least 4 cars.150 + 500x ≥ 2000. He needs to sell at least 4 cars.
C 500 + 150x ≤ 2000. He needs to sell at least 10 cars.500 + 150x ≤ 2000. He needs to sell at least 10 cars.
D 500 + 150x ≥ 2000. He needs to sell at least 10 cars.500 + 150x ≥ 2000. He needs to sell at least 10 cars.
The correct equation is:
150 + 500x ≥ 2000
To solve this equation, we need to isolate the variable x:
500x ≥ 2000 - 150
500x ≥ 1850
Divide both sides by 500:
x ≥ 1850/500
x ≥ 3.7
Since you cannot sell fractional cars, the minimum number of cars Bryan needs to sell is 4 (rounding up from 3.7), which matches option A.
