it cost $7.50 to enter a petting zoo. Each cup of food to feed the animals is $2.50. if you have $12.50, how many cups can you buy? Use a bar diagram to solve arithmetically. Then use an equation to solve algebraically
let y be your total moneyx is the number of cup of food you can buym is the cost per cup of food to feed the animalb is the cost to enter the petting zoo y = mx + bsubstitute the given values 12.50 = 2.50x + 7.50solve for x 12.50 - 7.50 = 2.50x5 = 2.50xx = 5 / 2.50x = 2 cups of food you can buy
