What is the total cost of a $12.60 item plus 7% sales tax?
Answers
To take a percent, move the decimal point of the percent two places to the left. 7% = 0.07
Then multiply:
12.60 • 0.07 = 0.88
12.60 + 0.88 = 13.48
The total cost is: $13.48
7% = 0.07 12.60 * 0.07 = 0.88 12.60+0.88 =13.48 $13.48 I hope this helps;)

Spencer took $21 with him to the mall. At the music store he spent 2/3 of his money on a DVD. Then spent 1/4 on a drink. How much money does spencer have left?
Answers
After the music store he had $14 left, because 21:3=7 and 7x2 equals 14.
After the drink, he has $3.5 left, because 14:4=3.5 and 3.5x1=3.5.
Conclusion: that is one expensive drink. (Answer is 3 dollars and 50 cents. Hope this helped:)
Ok to solve this problem we need to first find how much he spend in the mall. We put the 2 fractions into like denominators which is 12. If we convert it we get a total of 11/12. So he spent 11/12 of his money. One way you can solve is by figuring out how much 11/12 is and subtract that by 21. Then you will get 19.25 21 minus 19.25 is 1.75 dollars. Another way is to just find out how much is 1/12 of 21. Then you will get $1.75. So Spencer has 1.75 dollars left. I hope this helps!
