Answer:
$2.66
Step-by-step explanation:
Step 1: Multiply the $5 to the family of 3
[tex]5 \times 3 = 15[/tex]
That's what they would have paid if they did not have a coupon. Now they have a coupon and only pay $7.
Step 2: Subtract what they paid from the result
[tex]15 - 7 = 8[/tex]
Now we have found how much they save altogether. To find how much they saved each;
Step 3: Divide the result found in step 2 by the family of 3
[tex]8 \div 3 = 2.66666\dots[/tex]
Each person saves approximately $2.66
