What s the total cost of a $12.50 item plus 7% tax? Is the question how do you find the answer?

Answers

Answer 1
Answer: so percent means parts out of 100 so
7%=7/100=0.7/10=0.07/1=0.07

so we want to find 12.50 +7% of 12.50

'of' can be translated as multiply



12.50+(0.07 times 12.5)=12.5+0.88=13.38

the total cost is 13.38

a shortcut is if you want to find cost+tax then
cost=1 and tax=0.07 so 1+0.07=1.07 so to find cost, just multply by 1.07

PLEASE HELP! I'M IN 7th GRADE...AND I NEED TO GET MY MATH HOME WORK DONE, AND MY PARENTS AR'NT HOME TO HELP MEE..THANK YOU!

Answers

A. since you already have $43.50 already saved you subtract that from the amount the bike cost so you can see how much more needs to be left to save and that gives you $72.50. Then you divide the amount your saving up every week from that. So $72.50 divided by $7.25 is 10 and thats how many weeks it will take to save.

B. Since you still have that $43.50 saved and you have a coupon for $20 dollars off . Add those together to see how much you have saved up which equals $63.50. The bike is $116 so you subtract the amount you have for the bike from $116 which is $63.50 and that equals $52.50 and thats how much more money you need. Then divide how much money needed by the amount your saving up a week, which is $8.75. So $52.50 divided by $8.75 is 6 and thats how many weeks it will now take to get the bike.
