Question

Tyson wants to buy some juice pouches. He has four options to choose from.

Which option has the lowest cost per pouch?

O A 8 pouches for $2.04

O B 10 pouches for $2.69

O C 12 pouches for $2.80

O D 16 pouches for $3.80

Answer 1

Answer: C.  12 pouches for $2.80

Explanation:

x = number of pouches

y = cost for having x number of pouches

To find the unit cost, divide y over x

For choices A through D we have the following unit costs

• y/x = 2.04/8 = 0.255
• y/x = 2.69/10 = 0.269
• y/x = 2.80/12 = 0.233 (approximately)
• y/x = 3.80/16 = 0.2375

We see that 0.233 is the lowest unit cost, so therefore, Choice C is the lowest cost per pouch.
