Answer:
After 5 weeks.
Step-by-step explanation:
Westley starts with $85 and saves $5 per week. So:
Buttercup starts with $10 and saves $20 per week. So:
When they have the same amount of money, the two equations will be equal to each other. Therefore:
Solve for x. Subtract 10 from both sides:
Subtract 5x from both sides:
Divide both sides by 15:
Westley and Buttercup will have the same amount of money after 5 weeks.
Answer:
180 rabbits
Step-by-step explanation:
<u><em>The correct question is</em></u>
The rabbit population in a certain area is 500% of last years population. There are 900 rabbits this year. How many were there last year?
we know that
900 rabbits represent 500% of last year population
Last year population represent 100%
so
using proportion
Find out how many rabbits represent a percentage of 100%
Answer:
30 miles
Step-by-step explanation:
Given: Drive to work in 45 min.
Bus would take to travel= 1 hr 15 min
Average rate on the bus is 16 mph slower than his driving rate.
Lets assume the average driving rate be "x" mph.
∴ Average rate of bus=
Now converting unit of time taken to travel to work.
Remember; 1 hours= 60 minutes.
Time taken for drive to work=
Time taken in bus to work= 1 hour and 15 minutes=
∴ Time taken in bus to work in hours=
Considering the distance remain constant to travel for work.
Next, forming an equation to find the value of x.
As we know,
⇒
Using distributive property of multiplication.
⇒
Adding both side by 20
⇒
Subtracting both side by 0.75x
⇒
Dividing both side by 0.5
⇒
∴
Hence the average rate for drive to work is 40mph.
Now, subtitiuting the value of x to find the distance travelled to work.
Distance travelled=
Hence, distance travelled to work is 30 miles.
