Question

Bobby bought 8 hot dogs and 4 cokes for $27.00. Kevin bought 10 hot dogs and 8 cokes for $37.50. What did Shrig pay for 3 hot dogs and 2 cokes?

Answer 1

Let cost of 1 coke = x, cost of 1 hot dog (HD) = y

Answer 2

1 hot dog and 2 cokes is 5,25
4 hot dogs and 2 cokes is 13,50

SO 3 hot dogs is 8,25, witch gives 1 hot dog = 2,75 and 1 coke 1,25

Answer 3

put the first phrase in the simplest format, in this case divided by 4, witch gives you the price of 2 hot dogs and a coke. the second its an adition of 2 hot dogs and 4 cokes to the first phrase, so just do the math and you find both the price of a coke and a hot dog. Its simple logic.
