Problema Solution
Jeff is responsible for buying supplies of food and medication for the dogs and cats at a local shelter. The food and medication for a dog cost twice as much as for a cat. He needs to provide supplies for 164 cats and 24 dogs, and his budget is $4,240. How much can he spend on each dog for food and medication?
Answer provided by our tutors
let
d = the cost of food and medication for one dog
c = the cost of food medication for one cat
the food and medication for a dog cost twice as much as for a cat
d = 2c divide both sides by 2
c = d/2
he needs to provide supplies for 164 cats and 24 dogs, and his budget is $4,240
24d + 164c <= 4240
plug c = d/2 into the last equation
24d + 164(d/2) <= 4240
by solving the inequality we get
d <= $40
