Final answer:
Gary would need 15.2 ounces of glue and 7.6 ounces of glitter to make 4 bottles of glitter glue. We arrive at these quantities by multiplying the amounts used for 1 bottle by 4.
Step-by-step explanation:
To determine how much glue and glitter Gary would need to make 4 bottles of glitter glue, we need to perform a multiplication operation based on the given quantities for 1 bottle. For 1 bottle, Gary uses 3.8 ounces of glue and 1.9 ounces of glitter.
So, for 4 bottles, we multiply these quantities by 4:
- Glue: 3.8 oz × 4 = 15.2 oz
- Glitter: 1.9 oz × 4 = 7.6 oz
Therefore, Gary would need 15.2 ounces of glue and 7.6 ounces of glitter to make 4 bottles of glitter glue.
