## mathhelp-please 3 years ago Hilda bought 4 orders of french fries at \$0.67 each,3 hamburgers at \$1.28 each, and 4 shakes at \$2.25 each. She paid 8.25% tax on the whole order.What other information is necessary to find Hilda's correct change?

1. PsychoTink

By correct change do you mean what she got back from her payment, in which case you would need to know that. Or do you mean how much she has to pay, in which case I see anything missing.

2. AngelDreamGurl

Nothing looks missing...

3. DoomDude

yup

The answers are A. Total cost of the order B.Amount she paid in tax C.Amount she gave the cashier D. Reason for buying the food

5. AngelDreamGurl

Oh! than C

Please explain if you get this

Why please I just want to understand.

8. AngelDreamGurl

because in order to find the change you have to have a starting amount

9. lgbasallote

well the A and B are already given...who needs a reason to know the change? o.O

10. PsychoTink

Well thing about it, what of those can't you find from the given information? And then what isn't relevant? You can determine the total just by simple math. You can determine the tax required because you can find the total and they gave you the tax %. It doesn't matter why she ordered.

It doesn't tell you to solve for it, just HOW to.

thanks to everyone who came to help

Right, you don't have to do it, but it's asking what information are you missing to be able to. They told you how much of everything she bought, and how much each item costs. So that together would give a subtotal if needed. All the info is there. It told you the percentage of tax she paid, so you have the information to find that. You don't know how much she gave the cashier. It's never mentioned in the problem. And knowing why she ordered food is moot, it lends nothing to the problem.

.....Weird then..... :?

15. PsychoTink

What is weird? Do you still not get it? If not, where are you confused?

That then the answer is not there;if they gave you all the information already.

Should I circle C,like AngelDreamGurl told me ?

18. PsychoTink

The answer is C. I was explaining why it was that and why it couldn't be the other three in my posts. Read them again. In that last one especially you'll see that I was giving an explanation for each answer you gave as possible, and said for one of them you don't know it.

oK,

I thought it was C too,

I was going to type that along with my question, but it wouldn't let me.
