Question

Johnny needs to save $24.00 to buy a new video game. Three weeks after saving he has $6.00. After 6 weeks he has $12.00. If Johnny continues to save at this rate, how many total weeks will he have saved money to reach his goal?



3 weeks
6 weeks
9 weeks
12 weeks

Thanks!

Answer 1

3 weeks save $6.00
So, to save $24.00
total week required
= 24/6 * 3 = 12 weeks

Answer 2

12 weeks

very easy..

pay attention in class.

Every 3 weeks Johnny earns $6.00.
Therefore,
after 3 weeks he'd have $6.00
after 6 weeks he'd have $12.00 (6+6=12)
after 9 weeks he'd have $18.00 (12+6=18)
and after 12 WEEKS he'd have $24.00 (18+6=24)

Answer 3

rate of savings = $6/3weeks and $12/6 weeks .... $2 a week.

savings = weeks * 2

if you want to know when savings is 24, then solve for that.

24 = weeks * 2

or weeks = 24/2 = 12

Answer 4

12 weeks
6/3=2
12/6=2
24/12=2

Answer 5

12 weeks

Answer 6

two answers:
9 weeks or 12 weeks

If we consider the amt gets doubled every three weeks it will take 9 months

If we consider the amt is increased by $6 every three weeks it will take 12 months

Answer 7

in three weeks
$6.0
in six weeks
$12.0
in 12 weeks
$24.00

Answer 8
