Question

A 9-pack of plastic cups costs $4.51. What is the unit price, rounded to the nearest cent?

$ ___ per cup

Answer 1

`\huge\boxed{\bf\:0.5 \: dollars }`

Explanation:

Given,

• Cost of 9 plastic cups = $4.51

We need to find the unit price OR the price of 1 plastic cup.

To find this, we need to divide the cost of the total nunber of cups bought by the number of cups bought. Then,

Cost of 1 cup

= Cost of 9 cups/9

= 4.51 / 9

= $ 0.5 (rounded price)

`\rule{150}{2}`

Answer 2

50 cents or $0.50

Explanation:

c = the cost of each plastic cup, the unit price.

9c = 4.51

/9 /9

c = $0.50 per cup

Each cup costs 50 cents or $0.50

Hope this helps!
