- MONEY A store sells barrettes for $2 each and combsfor $1. Shelby buys 3 barrettes and a comb. Ashleybuys 2 barrettes and 4 combs. Write an expression forthe amount the two girls spent all together. Find thetotal amount spent.

Answer 1

We have that a store sells barrettes for $2 each and combs for $1.

According to this, if Shelby buys 3 barrettes and 1 comb, this is equivalent to the following amount of money spent by Shelby:

3($2) + 1($1)

Now, if Ashley buys 2 barrettes and 4 combs this is equivalent to the following amount of money spent by Ashely:

2($2) + 4($1)

Then, the expression for the amount the two girls spent all together is:

3($2) + 1($1) + 2($2) + 4($1)

this is equivalent to:

Total amount spent = 5($2) + 5($1)

According to the above expression, we can conclude the total amount spent is

Total amount spent = 5($2) + 5($1) = $10 + $5= $15

So that, we can conclude that the correct answers are:

Expression for the amount the two girls spent all together :

Total amount spent = 5($2) + 5($1)

Total amount spent:

$15
