Hope this helps!
X + y = 22,102
.11x = .07y + 913.46 = x= (7/11)y + 8304.18
((7/11)y + 8304.18) + y = 22,102
(18/11)y = <span>13797.82
</span>
y= 13797.82/(18/11)
y=8432.00
8,432.00 dollars are invested at 7%
13,670.00 dollars are invested at 11%
Check
.07 x 8432= 590.24
.11 x 13,670 = 1503.70
1503.70 - 590.24 = 913.46
Find the difference between x and y, so 3 and 27, the difference is 9. To see if its constant, put it into 9*8, which is 72, so the constant is 9. To find the answer in the blanks, plug in 9 and the number to find the answer.<span />
16.99 every 30 minutes
3 hours = 180 minutes + 45 minutes
225 minutes.
225/30 = 7.5
16.99(7.5) = 127.43
