Elis [28]
If the time she rode her bike is 24, then 24*3 would be the Whole time she was there. She was there for a total of 72 hours.
Subtract 24 from 72 because it's 1/3 and you need the other time.
You get 48.
You need to find 1/4 of 48, so you divide it by 4.
48/4 = 12.

Answer:

Buy the batteries and stereo online:  

4.99*2= $9.98 +$90 = $99.98  

6.99-5.00 = $1.99  

99.98+1.99=$101.97  

3Cds in store  

7.97*3= $23.85  

5% tax = 1.19  

10% off = 2.39  

$23.85 - $1.19= $22.66  

22.66 + 101.97= $124.63  

All in store:  

12+100+23.85= 135.85 - 6.45 = $129.40  

All online:  

9.98 + 90 + 26.85= 126.85 +$1.99 = 128.84
