A certain shampoo is available in two sizes. A 23.7-ounce bottle costs $4.97 . A 33.8 -ounce bottle costs $7.48. Find the unit price for each size. Then state which size is the better buy based on the unit price. Round your answers to the nearest cent.

Verified Answer :

2.37 divided by 4.97 = 4.8 per unit for bottle one

33.8 divided by 7.48 = 4.5 per unit for bottle two
 Bottle two is the better buy because it is 3 cents cheaper

Answer:

Bottle one will be better to buy based on unit price of the shampoo.

Step-by-step explanation:

For bottle one - amount of shampoo in unit price

= \(\frac{\text{amount of shampoo in the bottle}}{\text{Total cost}}\)

= \(\frac{23.7}{4.97}\)

= 4.8 ounce per dollar

For bottle Two -  amount of shampoo in unit price

= \(\frac{\text{amount of shampoo in the bottle}}{\text{Total cost}}\)

= \(\frac{33.8}{7.48}\)

= 4.5 ounce in one dollar

First bottle is better to buy because we are getting more (0.30 ounce) shampoo in one dollar.
