At the super market, Michaela spent $117 on 9 frozen dinners that each cost the sameamount. She kept 3 of the dinners and gave the rest to her friend. Which expressionrepresents the total cost of the dinners that Michaela gave to her friend?

Answer :

Given:

$117 was spent on 9 frozen dinners

Total dinners = 9

Total amount = $117

Step 1: Find the number of dinners she gave to her friend

Dinner given to her friend = Total dinner - how many she kept

=> 9 - 3 = 6

Therefore, 6 dinners were given to her friend

Step 3: Find the fraction of the dinner given to her friend to the total dinners

[tex]\frac{dinner\text{ given to friend}}{Total\text{ dinners}}=\frac{6}{9}[/tex]

Step2: Find the cost of dinner

This will be obtained by multiplying the total cost by the fraction

[tex]\text{ \$117 x }\frac{6}{9}[/tex]

Option A is correct
