Hiro bought a five-pack of rechargeable batteries last week and an eight-pack
of the same type of batteries this week. He knows the cost of each battery is
the same no matter how many are in a pack. If Hiro spent $5.55 more on the
eight-pack than on the five-pack, how much would a ten-pack cost?

Step-by-step explanation:

Let x represent the cost of each battery since the cost of each battery is the same no matter how many are in a pack.

Hiro bought a five-pack of rechargeable batteries last week and an eight-pack of the same type of batteries this week. It means that the cost of the 5 pack battery is $5x and the cost of the 8 pack battery is $8x.

If Hiro spent $5.55 more on the

eight-pack than on the five-pack, it means that

8x = 5x + 5.5

8x - 5x = 5.5

3x = 5.5

x = 5.5/3 = 1.83

The cost of a 10 pack battery would be

1.83 × 10 = $18.3

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
