As a membership fee a health club charges a one time amount of $40 and charges $25 for each month. The total fee after m months
is $240. What is the value of m A runner warms up for ten minutes and then takes seven minutes to run each mile. The total time after r miles is 45 minutes. How many miles are run?
First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months. To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x. 240 = 25x + 40 subtract 40 from each side 200= 25x divide by 25 8 = x 8 months
