Answer:
Compare the cost for the each (smallest) unit.
Step-by-step explanation:
You can calculate the cost per unit
For example :
20 ounces of water of brand A cost 1.50
30 ounces of water of brand A cost 2
20 ounces of water cost 1.50/20 = 0.075 dollar per ounce
30 ounces of water cost 2/30 = 0.0677 dollar per ounce
2300 cups because if 460 is 20%, multiply the 460 x 5 to get 100%
Answer:
15 weeks
Step-by-step explanation:
Let the number of weeks = x.
At the end of x weeks,
Jeremy has 120 + 14x,

4x = 60
x = 15
