Stella buys one carton of juice. The carton holds 130 fl oz. She fills 5 glasses with juice from the carton. Each glass holds 8 fl oz. How much fl oz is left in the carton?

First, we find out how much juice was poured into glasses from the carton:
Poured Juice Weight = Glasses of Juice * Ounces per glass
Poured JuiceWeight = 5 * 8
Poured JuiceWeight = 40

Next, we subtract the poured out juice weight from the full carton weight to find out the leftover amount:
Leftover Juice = Carton Weight when full - Poured Juice Weight
Leftover Juice = 130 - 40
Leftover Juice = 90 oz
