-3(x-1)+8 (x-3)=6x+7-5

Jennifer is saving money to buy a bike. The bike costs $326. She has $131 saved, and each week she adds $15 to her savings. How
motikmotik

Answer: It should take her 13 weeks.

Step-by-step explanation:

If the bike costs $326 and she already has $131, we can subtract 131 from 326. 326-131=195. Now we know that Jennifer needs $195 dollars. Next, since she adds $15 each week, divide 195 by 15. 195/15= 13. It should take Jennifer 13 weeks so save up for her bike.

Paha777 [63]
For this case we can make the following rule of three:
 1507 ----> 100%
 1213 ----> x
 Clearing the value of x we have:
 x = (1213/1507) * (100)
 x = 80.4910418
 Rounding off we have:
 x = 80.5%
 Answer:
 
this player has made 80.5% of free throws
