Use the information below and in the table.

Ashley is selling chocolate bars for $\$1.50$ each to raise money for the band.

17. Write an expression to represent the total amount of money Ashley raised during this week.

Step-by-Step Solution

Answer

Expression to represent the total amount of money raised during this week is 

$A=\left(10\times 1.50\right)+\left(15\times 1.50\right)+\left(12\times 1.50\right)+\left(8\times 1.50\right)+\left(19\times 1.50\right)+\left(22\times 1.50\right)+\left(31\times 1.50\right)$

Step 1 - Observation from image

From the given image, write the number of chocolate bars sold in each day of given week.

• On Monday, number of chocolate bars sold is 10.
• On Tuesday, number of chocolate bars sold is 15.
• On Wednesday, number of chocolate bars sold is 12.
• On Thursday, number of chocolate bars sold is 8.
• On Friday, number of chocolate bars sold is 19.
• On Saturday, number of chocolate bars sold is 22.
• On Sunday, number of chocolate bars sold is 31.

Step 2 - Amount raised each day

As, chocolate bars are selling for $\$1.50$ each. So amount raised each day is:

• On Monday, amount raised is $10\times 1.50$ 
• On Tuesday, amount raised is $15\times 1.50$
• On Wednesday, amount raised is $12\times 1.50$
• On Thursday, amount raised is $8\times 1.50$
• On Friday, amount raised is $19\times 1.50$
• On Saturday, amount raised is $22\times 1.50$
• On Sunday, amount raised is $31\times 1.50$

Step 3 - Write expression to represent total amount during this week

To write expression to represent total amount $\left(A\right)$  during given week, add the amount raised by each day of this week.

$A=\left(10\times 1.50\right)+\left(15\times 1.50\right)+\left(12\times 1.50\right)+\left(8\times 1.50\right)+\left(19\times 1.50\right)+\left(22\times 1.50\right)+\left(31\times 1.50\right)$
