At a car dealership, 72 trucks were sold in one month. If 60% of
the total vehicles sold were trucks, how many total vehicles were
sold that month?
A 12
B 132
C 120
D 160
Answer:
The total number of vehicles is: x = 120
Hence, option C is correct.
Step-by-step explanation:
Total trucks that were sold in one month = 72 trucks
Let 'x' be the total number of vehicles.
Given that 60% of the total vehicles sold were trucks.
Thus,
60% of x = 72
60/100 × x = 72
x = [72 × 100] / [60]
x = 120
Therefore, the total number of vehicles is: x = 120
Hence, option C is correct.
Answer:
C 120
Step-by-step explanation:
