5. Kamaya's biology class requires 580 pages of reading over the course of the school year. Her history class requires 130 pages than her biology class. Write an equation that models this situation. 6. A diner charges $1.35 for a cup of coffee and $0.59 for refills. Which equation could be used to find the cost c of a cub of coffee with r number of refills. a. c = 1.35 + 0.59r b. 1.35c + 0.59 = r c. 0.59r - 1.35 = c  d. c = 1.35 - 0.59r
