The shop has 1260 ounces of cranberry juice and 650 ounces of passion fruit juice. ifvthe juices are used to make crazy cranberry smoothies, which juice will run out first? how much of the other juice will be left over?

Given:
Each smoothie requires 20 ounces of cranberry juice and 10 ounces of passion fruit.
There are 1260 ounces of cranberry juice.
There are 650 ounces of passion fruit juice.

For the maximum servings of the smoothie, let
x = the number of 20-ounce cranberry juice used,
y = the number of 10-ounce passion fruit juice used.

The cranberry juice runs out when
20x = 1260
x = 63  servings 

The passion fruit juice runs out when
10y = 650
y = 65 servings

Because x reaches, the cranberry juice runs out first after 63 servings of the smoothie.
There will be two 10-ounces = 20 ounces of the passion fruit left.

 
(a) The cranberry juice runs our first.
(b) There will be 20 ounces of the passion fruit left over.

Ithink the answer should be b.
