Lets say x = 89.99 and y = 56.49
P% * x = y
P% = y/x
56.49/89.99 = 0.6277
0.6277 * 100 = 62.77
But because we are looking for how much off the sale is:
100% - 62.77%
= 37.23%
The sale price is 37.23% off.
Answer:
3 packages
Step-by-step explanation:
There are 1000 m in 1 km, so 2500 m is the same as 2.5 km.
1 package = 2.5 km
2 packages = 5.0 km . . . . still too little
3 packages = 7.5 km . . . . more than sufficient
Annabelle needs 3 packages of yarn to satisfy her requirement for 7 km.
