To find the percentage of something, simply multiply the percentage (converted into a decimal) and the total. 60% = 0.6. 0.6*1.15 = 0.69.
The markup is $0.69.
To find the retail price, add the markup to the wholesale cost. 0.69+1.15= 1.84.
The retail price is $1.84.
Hope that helped you.
So that is equal to 180 miles per 2 hours which is 90 miles per hour if each hour has the same m/hr rate.
You can set up a proportion:
let x = number of miles per hour

cross multiply and you get
2x=180
divide both sides by 2 and you get
x=90
so you get the same answer both ways,
90 miles per hour
Ok so I did 25 divided by 2 I got 12.5 and 26 divided by 3 and got 8.6 so the best deal would be 8.6 for part A .
