Question

At bjs you can buy 6 cans for $4.99 or 10 cans for 7.99. Which pack is a better buy?

Answer 1

For this, you have to calculate the Unit value,

Unit value of 1rst one,  4.99/6 = 0.83

Unit value of 2nd one, 7.99/10 = 0.79

As, 2nd one is cheaper, so it is better :))

Answer 2

Answer with Step-by-step explanation:

You can buy:

6 cans for $4.99

i.e. 1 can for $4.99/6

i.e. 1 can for $0.83

or 10 cans for $7.99

i.e. 1 can for $7.99/10

i.e. 1 can for $0.799

Since, cost of 1 can on buying 10 cans for $7.99 is less than the case on buying 6 cans for $4.99

Hence, Pack which is better is:

10 cans for $7.99
