You have a $25 gift card for a bagel shop. A bagel cost $1.25 write a equation that gives the amount (in dollars) that remains on the card as a function of the total number of bagels you have purchased so far. How much money is on the card after you buy 2 bagels.?

Let the variable "b" represent the number of bagels you buy

let the variable "R" represent the amount of money you have left

R = 25 - 1.25b

is your equation

then to find out after you bought 2 bagels

R = 25 - 1.25 (2) = 25 - 2.5 = 22.5

do you would have $22.50 left on the card after you buy 2 bagels
