13,500 at 5.2 for 8 years compounded semi-annually.
Total = Principal * (1 + rate/n) ^n * years
where "n" = number of compounding periods per year.
Total = 13,500 * (1 + .052 / 2) ^ 2 * 8
Total = 13,500 * (1.026) ^ 16
Total = 13,500 * 1.5078487226
Total = 20,355.96

Answer:
y = 60
Step-by-step explanation:
From the information we get:
x quantity of 4 dollars coffee used in the mix
y quantity of 7 dollars coffee used in the mix
For the quantity of coffee to be sold a 7 $/pound ( 90 pounds)
Then 6*90 = 540 $
Therefore
x + y = 90 and
4*x + 7*y = 540
A two equations system we solve for x and y
y = 90 - x
4*x + 7* ( 90 - x ) = 540
4*x + 630 - 7*x = 540
- 3*x = - 90
x = 30 pounds and
y = 90 - 30
y = 60
We should use 60 pounds of the seven $ coffee
300000+70000+3000+600+90+8
