Question

Consider the following advertisement.Which of the following calculations represents the cost of 2 dozen iris bulbs?

Answer 1

Answer:

C: (6 x $5)+(6 x $4)+(12 x $3)

Explanation:

The total number of bulbs bought = 2 dozens = 2 x 12 = 24

• The cost per bulb for the first half-dozen = $5

$\text{Cost for the first half-dozen=6 x \ 5}$

• The cost per bulb for the next half-dozen = $4

$\text{Cost for the next half-dozen=6 x \ }4$

Out of 24 bulbs, we have calculated the cost for 12.

• The number of bulbs left = 24 - 12 = 12.

,

• Each additional bulb is $3 per bulb.

The cost for the last 12 will be:

$12\times\ 3$

Therefore, the cost for the 2 dozen iris bulbs will be:

$(6\times\ 5)+(6\times\ 4)+(12\times\ 3)$

The correct choice is C.
