Question

After all, tryouts are completed, the school will be hosting a party for all the new athletes. At the party, hot dogs and hamburgers will be provided to all athletes and their guests, if they choose to bring a guest. The ratio of hot dogs purchased to a number of guests is 1:0.8. Determine how many hot dogs you would need if 150 people attend the party.

Answer 1

Answer:  120

Explanation:

h = number of hot dogs

The ratio of people to hot dogs is 1:0.8

If 150 people show up to the party, then

(number of people)/(number of hot dogs) = 1/0.8

150/h = 1/0.8

150*0.8 = h*1 ... cross multiply

120 = h

h = 120

You'll need 120 hot dogs.
