Question

A gift shop sells candles and flower bouquets. Each candle costs $8 and each flower bouquet costs $26. On Monday, the gift shop sold c candles. On the same day, the gift shop sold 9 more candles than flower bouquets. Which of the following expressions represents the gift shop's total income from the sale of these candles and flower bouquets?
A.
$8c + $26(c - 9)

B.
$8c + $26(c + 9)

C.
$26c + $8(c + 9)

D.
$26c + $8(c - 9)

Answer 1

Let c = the number of candles sold.

Let b = the number of bouquets sold.

 

We know that each candle costs $8 and each bouquet costs $26.

 

Therefore, the total income for any day is as follows:

 

$8 * c + $26 * b

 

The problem also tells us that the shop sold 9 more candles than bouquets.

Therefore, we know that c = b + 9, which means b = c - 9

 

With this information, you can substitute this value of b into the equation to get your answer.

Answer 2

Very important:    Cost for group of items = ($ per item)*(number of items)

 

Total income =  income from candles      +   income from flowers

Total income =    $8c                             +      $26f

 

   But,      c = f+9              ["9 more candles than flower bouquets"]

               f = c-9

 

So,

 Total income =  $8c + $26(c-9)

 

Check:  how about  f=4; what is c ?

    "9 more candles than flower bouquets"

       c = 13

 Total income = $8(13) + $26(4)       [13 is 9 more than 4]

Answer 3

What you want is to make each term only have units of dollars.  So, you sum up the product of the number of each item and its cost.  For this problem it would be

 

(cost of 1 candle in $/candle)(number of candles) + (cost of 1 bouquet)(number of bouquet).

 

The answer is 8c + 26(c + 9)
