Answer:
$800
Step-by-step explanation:
if $320 is 40% then we multiply to find 100% of the goal so we multiple each side by 2.5.
So,
320
<u>x 2.5 </u>
Dividing by a fraction is the same as multiplying with the opposite of the fraction. 8/9 / 3/4=8/9×4/3=32/27=1 5/27.
r=4
15r-6r=36
9r=36
r=36/9
1526.25 so in one day the interest will have added 26.25
