Question

Marie purchased b burritos for $5.50 each and paid $7 extra for a service fee. The total cost of Marie's purchase was $62. How many burritos did Marie buy?

Answer 1

Answer: 10 burritos

Explanation:

This is a worded question. The first step would be to extract the essential information and represent it as an easily understandable equation:

b is the number of burritos

$5.50 is the cost for each burrito

$7 is additionally charged for a service fee

We have to find the number of burritos (b)

Therefore, we can write the equation like this:

(5.50 * b) + 7 = 62

We can then rearrange the equation to get b on one side. Remember to follow the BIDMAS rules backwards!

(5.50 * b) + 7 = 62

5.50*b = 62-7

5.50*b = 55

b = 55/5.50

b = 10

Finally, always write a worded answer because it is a worded equation. For example, you could write:

Marie bought 10 burritos

Hoped this helped!

Answer 2

Answer: 10 burritos

Explanation:

Let y be the total cost, and b is the number of burritos

So we have the equation is

y= 5.50b + 7

Now we put a total cost of $62 in the y spot

62 = 5.50b + 7

Subtract 7 from both sides

55 = 5.50b

Divide 5.50 from both sides

b = 10 burritos
