David practices piano for 1 1/3 hours on monday and 3 1/2 hours on tuesday how much longer does he practice piano on tuesday that on monday. a 1 1/5. b 2 1/6. c 2 2/5. d 2 5/6.

B. 2 1/6

Step-by-step explanation:

Change both mixed fractions into improper fractions.

1 1/3 =4/3

3 1/2 =7/2

Find a common denominator for both. 8/6 and 21/6.

then subtract them to get 13/6.

Then change back into an improper fraction. 2 1/6

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

i think the amount would be $140.62
