Answer:
The answer is C becuase 18÷3=6
Gabrielle is x years old.
Felicia is 6 years older.....so Felicia is x + 6
the mom is twice as old as felicia...so the mom is 2(x + 6)
the aunt is x years older then mom....so the aunt (tanya) is 2(x + 6) + x
so Tanya/s age is :
2(x + 6) + x =
2x + 12 + x =
13x + 12 <===
Ok, first set this up as an equation with your given variables. You know that Sylvie bought 1 container of cream cheese, which is $2.95, and you know that Sylvie spent $7.50
<u>(my best assumption is this is the subtotal)</u><u /> on the cream cheese and 13 bagels. As an equation, it would come out as:

To start solving the algebraic equation, wou can subtract 2.95 on both sides, resulting as

Now, to get "b" by itself, you must divide
13 on both sides, resulting as

This will answer your question as the cost of 1 bagel would be
$0.35 per bagel.
