Giselle spent a total of $43 when she went shopping. She spent $14 for socks, $18.75 for a wallet, and bought lunch. When she got home, she had $4 left. How much did she spend for lunch?

Answer 1

Solve for x.

14 + 18.75 + x + 4 = 43

36.75 + x = 43

x = 43 - 36.75

x = ?

Answer 2

Why do you add the $4? My daughter missed this on a homework sheet because she didn't use the $4. Why should that even be considered?

Answer 3

We're trying to find out how much she spent for lunch. We can account for the rest of the money.

Another way to work this problem is:

14 + 18.75 + x = 43 - 4

You'll get the same answer.

Answer 4

Thanks, but that still makes no sense.

If she SPENT a TOTAL of $43 which included $14 for socks and $18.75 for a wallet and had $4 LEFT, Why does the $4 even have to be in the equation?

$43= $14 + $18.75 + LUNCH (X)

Answer 5

I see your point. The question states that she SPENT $43. I suggest you have your daughter ask her teacher.

Answer 6

The $4 only enters the picture if asked ,
"how much money did she start with"

it said,
14 + 18.75 + lunch = 43
lunch = 43 - 14 - 18.75 = 10.25

So her lunch cost $10.25

She started with 43+4 or $47
