Answer:
The TRUTH about the soap purchasing options is:
d) it is better to but the 10-ounce bottle because the price per ounce is cheaper.
Step-by-step explanation:
a) Data and Calculations:
Cost of 10 ounce bottle of soap = $2.00
The per ounce cost of the 10-ounce bottle of soap = $0.20 ($2/10)
Cost of 20 ounce bottle of soap = $5.00
The per ounce cost of the 20-ounce bottle of soap = $0.25 ($5/20)
Therefore, the 10 ounce bottle of soap is cheaper and better.
b) It is more cost-effective to buy the 10 ounce bottle of soap. With $4.00, one can buy 2 of 10 ounce bottle of soap unlike $5.00 spent for 20 ounce bottle.
