### Instruction:
Louis has 5 oranges and 3 apples. Samantha has 8 oranges and 7 apples. If Marley has twice as many oranges as Louis and three times as many apples as Samantha, how many fruits in total does Marley have?

### Response:
The total amount of oranges that Marley has is twice the amount of oranges that Louis has 5*2=10 oranges
Marley also has thrice the amount of apples that Samantha has, which totals to 3*7= <<3*7=21>>21 apples.
In total, Marley has 10+21 = <<10+21=31>>31 fruits
