Q. The ratio of new car sales to used car sales at the car lot is 3:5. If the total car sales were $287,400 last month, what was the total of the used car sales?
Define Equations: Let's denote the total amount of new car sales as 3x and the total amount of used car sales as 5x, where x is the common ratio multiplier. According to the problem, the sum of new and used car sales is $287,400.So, the equation based on the given information is:3x+5x=$287,400
Combine Like Terms: Now, we combine like terms to simplify the equation:3x+5x=8xSo, the equation becomes:8x=$287,400
Solve for x: Next, we solve for x by dividing both sides of the equation by 8:x=8$287,400x=$35,925This means that the common ratio multiplier for the car sales is $35,925.
Calculate Total Used Sales: Now that we have the value of x, we can find the total of the used car sales by multiplying the common ratio multiplier for used car sales (5) by x: Total used car sales = 5x Total used car sales = 5×$(35,925) Total used car sales = $(179,625)
