If you multiply 23 by 12 you will get 276.
Well, first you go to make a equation like... 35 x 15/100.Then all u gotta do is find y, which is gonna be 5.25. The shirt will cost $5.25
answer for this question is 3.85 units squared
C) $694.25
Why?
Because you want to times the interest by 2 (1 is for one year but u want to find the amount after two years) then you multiply the amount given to each bank separately so:
400*0.07 (7% which is 7/100) = 28
250*0.065 (6.5% which is 65/1000) = 16.25
Then u add the interests together:
28+16.25 = 44.25
Finally you add that to the amount you started with:
$650+$44.25= $694.25
