Step-by-step explanation:
60% = 0.6
15% = 0.15
10 = 0.15
Answer:
24
Step-by-step explanation:
Let x represent total number of vehicles
Let T represent number of trucks
Let V represent number of vans
Let B represent number of buses
Convert percent's to decimals:
60% = 0.6
15% = 0.15
Set up equations:
T = 0.6x
V= 0.15x
B= (1 - 0.6 - 0.15)x
For buses, the remaining portion of the 100% of vehicles is 100% -60% -15%
Since we know there are 10 buses, set B=10
B= (1 - 0.6 - 0.15)x
10= (1 - 0.6 - 0.15)x
10= 0.25 x
Divide both sides by 0.25 so that we get:
10/0.25 = x
x= 40
We now know there are 40 vehicles present. To find the number of trucks, we take 60% of the total number of vehicles
T = 0.6x
T= 0.6 (40)
T= 24
Therefore there are 24 trucks.
