The marked price of an article is 25% above its cost price when it is sold at a discount of 15%
First you make an equation and establish a variable.
x=amount of hours the DJs will charge the same amount
100+21x=150+15x
Now you solve for x and that will get you your answer.
100+21x=150+15x
-21x -21x
100=150-6x
-150 -150
-50=-6x
8.3333...=x
You can round the answer to $8.33
Hope I helped.
So find how much the racer needs to cover more
she covered 20 and needs to cover 75
75-20=55
she needs to cover 55 more
so 10 km per hour
10 times x hours=55 miles
divide both sides by 10
x hours=5.5
since you want whole hours, we round up so she at least gets there
6 hours is the answer
