Emily brought some money on a trip to the aquarium. She used half of the money to buy an admission ticket. Then, she $8 used to buy lunch at the food court. She used 3/4 of what was left to buy a souvenir, leaving her with . How much money did Emily take to the aquarium?
Let the total money be x. 0.5x + 0.75(0.5x) + 8 = x You'll get the answer if you solve this.
Hmmmm is the first term correct? Does 0.5x mean half her money or does it mean half of the money she has left? I think we need to fix this.
well it is on working problems backwards if that helps any?
0.5 x means half the money. You can also write it as x/2.
Am I right meverett?
another copy and paste fail.
Then, she $8 used to buy lunch at the food court. She used 3/4 of what was left to buy a souvenir, leaving her with ????
That's not what you should find.
The answer is approximately 64.
I agree with satellite, can we look at the question again? pratu unfortunately 0.5x is not half of the original money, it is 0.5 of the ending money.
thank you!! @pratu043
welcome
at the risk of repeating myself, and pratu's answer notwithstanding, there is a copy and paste failure here. how much money she is left with determines how much she started with, and that came up as a blank space in the question
well it was a muti. choice answer.
and not to be rude but in fact pratu's answer is simply wrong.
what mistake did I make?
okay then i could be 50/50 what do you think?
ok one more time when you copied and pasted the question here, one piece was missing. look at this line here leaving her with . there should be a number between the "with" and the "."
one sec.
leaving her with $100? leaving her with $1? leaving her with 1 cent?
oh i see... leaving her with $4
oh, so it must be 8 + 4?
yes,
