Answer: 2 inches
Explanation: The area formula is length times width (L*w=a). We know that the area is 64in^2 (a=64) and the length is 32in (L=32), so we put those values into the equation and get 32*w=64. We then get w by itself by dividing both sides by 32, and get w=2. so the width is 2 inches.
The 114 represents 80% of the total price before the sale. You would set up your equation as
Cost Price * 80% = Sale Price.
Sale Price = 114
80% = 80/100 = 0.8
Cost Price = 114/0.8
Cost Price = 142.50 which is the price before the deduction. You can confirm this by taking 20% of 142.50 and subtracting it form 142.50
20% * 142.50
20/100 * 142.50
2850/100
28.50
Now subtract 28.50 from 142.50
142.50 - 28.50 = 114 which is just what you might expect.

Answer:
0.27 cubic feet of mulch is remaining
Step-by-step explanation:
Quantity in the bag = 2 7/16 cubic feet of mulch
Quantity used = 8/9 of the bag in his garden
Mulch used = 8/9 of 2 7/16
= 8/9 × 39/16
= 1/9 × 39/2
= 39/18
= 2 3/8 used
Total mulch left = Total mulch in the bag - mulch used
= 2 7/16 - 2 3/8
= 39/16 - 39/18
= 702-624/288
= 78/288
= 0.27 cubic feet of mulch is remaining
