Answer:
24 cars
Step-by-step explanation:
out of 80 toys, 3/5 are buses- 80 * 3/5 is 48 so there are 48 buses
80 - 48 is 32, 32 of the rest of the toys are cars and bikes
we know that there are 3 times as many cars than bikes, so to find out how many cars and bikes there we can do 3n + n, where n is the number of bikes it also equals 4n
32 = 4n; n = 8
there are 8 bikes, so there are 24 cars
Try this solution:dy/dx=y⁴cosx; y⁻⁴dy=cosxdx;

Here you will divide 500 by 6 to get the girl students, and 500 by 5 to get boys.
Do you have a picture or is it a word problem?
$50 per day x 6 days = 300
20% = 0.2, times t = 0.2t
The equation would be: f(t) = 300 + 0.2t
