A total of P60,000 was invested, a portion at 5% and the remainder at 4.5%. The total amount of interest earned was P2,900. How
much was invested at each rate?
1 answer:
Answer:
P40000 at 5%
P20000 at 4.5%
I am curious as to what the P stands for. Can you tell me?
Step-by-step explanation:
Let x = amt. invested at 5%
y = amt. invested at 4.5%
(1) x + y = 60000 (2) .05x + .045y = 2900
50x + 45y = 2900000
-45 times (1) <u>-45x - 45y = -2700000 </u>
5x = 200000
x = 40000
40000 + y = 60000
y = 20000
P40000 at 5%
P20000 at 4.5%

Answer:
29 and -18
Step-by-step explanation:
f(x)= -3x+12
f(-9)= -3(-9)+2
f(-9)= 27+2
f(-9)= 29
g(x)= x2
g(-9)= -9(2)
g(-9)= -18
Y = 3x + 5 because the slope is 3/1 and 0 = 5
