vvvv
Step-by-step explanation:
1. Make it so 1/4 is an eighth so you can subtract it from 5/8.
1/4 x 2 = 2/8
2. Subtract 2/8 from 5/8.
5/8 - 2/8 = 3/8
Daniel ate 2/8s of the left over pie, and there is 3/8s remaining.
800 + 16x = 720 + 21x. Cancel out the 720 to get 80 + 16x = 21x. Subtract 16x from both sides to get 80 = 5x. Divide by 5 to get 16 = x, or x = 16. 16 hours. The charge is 800 + 16(16), = 720 + 21(16) which = 800 + 256 = 720 + 336 which = 1,056 = 1,056. Hope this helped!
