Answer:
The solutions are:
It would be the bottom because think if you put 500 in an account and pay it annually you would add it because he's paying annually and that means every time he pays your adding to your account
3 weeks
Step-by-step explanation:
To find the number of weeks, we have to equate the amount already saved and planned to save by both each week.
So we can write the expression as,
Let w be the number of weeks.
25 + 5w =16 + 8w
Grouping the terms as,
25 - 16 = 8w - 5w
9 = 3w
Dividing both sides by 3, we will get,
3w/3 = 9/3
w = 3
So number of weeks = 3
Answer:
A
Step-by-step explanation:
22-10=12
total cost=5+12×0.50
=5+6
=11 $
This is actually quite simple. all you need to do with a question like this is divide the interest by the principal, and you get the percent answer to the rate. the answer would be approximately 7.3%.
