A conference spent $108 on 154 servings of cantaloupe and honeydew. If a cantaloupe melon costs $3 and serves four
while a honeydew melon costs $4 and serves six, how many honeydew melons did the organizers buy?
~~~~~~~~~~~
Let x = the number of honeydew servings.
Then the number of the cantaloupe servings is (154-x).
Each single honeydew serving costs = dollars;
Each single cantaloupe serving costs dollars.
Write the money equation
= 108 dollars.
Multiply both sides by 12
8x + 9*(154-x) = 12*108.
From the equation
x = = 90.
90 honeydew servings means = 15 honeydew mellons.
ANSWER. 15 honeydew mellons.
