Ataxi charges a flat rate of $1.75, plus an additional $0.65 per mile. if erica has at most $10 to spend on the cab ride, how far could she travel?
answer: 12.69 miles approx
let x represent the number of miles traveled
1.75 + 0.65x = 10
0.65x = 8.25
x = 12.69 miles approx
the markup rate is 51% on the cost
price of book = 7.99
cost to the store = 5.29
the markup rate is a term used to figure what percentage is added on to the cost of the item to find its selling price.
if we subtract cost from the price we will know how much is added to actual cost: 7.99 - 5.29 = 2.7
markup rate is 0.51*100 = 51%
