Question

The ratio of hot dogs to hamburgers is 17:13. The total amount of hot dogs and hamburgers for the party is 390. How many of each do you have?

Answer 1

221 hotdogs

169 hamburgers

Explanation:

Let 17x = no. of hotdogs

and 13x = no. of hamburgers

17x + 13x = 390

30x = 390

x = 13

17x = 17(13) = 221 hotdogs

13x = 13(13) = 169 hamburgers

Answer 2

There are 221 hot dogs and 169 hamburgers

Explanation:

(If you need me to explain a little clearer, please comment so I can edit!)

17 : 13 = 30

x : y = 390

390 ÷ 30 = 13

17 · 13 = x

221 = x

13 · 13 = y

169 = y
