We have been given that Anna and Joe's father donated $3 for every lap they swam in a swim-a-thon Ann swam 21 laps and Joe swam 15 laps. We are asked to find the amount of money their father donated using distributive property.
Therefore, the amount of money donated by their father was $108.
Since she bought 4 bags of 50 beads and 3 bags of 200 beads you only need to use two operations: multiply and add.
4 x 50 is 200
3 x 200 is 600
600 + 200 = 800
Mariah purchase 800 beads in total.
