The simple interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above and solve for t
![t=[(645/600)-1]/0.025=3\ years](https://tex.z-dn.net/?f=t%3D%5B%28645%2F600%29-1%5D%2F0.025%3D3%5C%20years)
Triangle Area = .5 * base * height
Triangle Area = .5*15*12
Triangle Area = 90
Answer:
1.50
Step-by-step explanation:
X = hot dog price
Y = hamburger price
5X + 4Y = 16.50
4X + 5Y = 17.25
4(5X + 4Y = 16.50)
20X + 16Y = 66
5(4X + 5y = 17.25)
20X + 25Y = 86.25
Now subtract the equations:
20X + 16Y = 66
20X + 25Y = 86.25
9Y = 20.25
Y = 2.25
Hamburger is $2.25
4X + 5(2.25) = 17.25
4X + 11.25 = 17.25
4X = 6.00
X = 1.50
Hamburgers are $2.25
Hotdogs are $1.50
