The amount he invested in Fund A was twice as much as the amount he invested in Fund B.
LEt x be the amount invested in Fund B
The amount invested in Fund A is 2x
Fund A returned a 8% profit
Profit amount for fund A is 2x * 8% = 2x * 0.08= 0.16x
Fund B returned a 2% profit
Profit amount for fund B is x * 2% = x * 0.02= 0.02x
total profit from the two funds together was S1800
Profit fund A + profit fund B = 1800
0.16x + 0.02x = 1800
0.18x = 1800
Divide by 0.18 from both sides
x = 10000
he invest $10,000 in Fund B
Step-by-step explanation:
x = -10, y = 10
y= -4x+4
m1×m2 = -1
-4 × m2 = -1
m2 = 1/4
y-y1 = m(x-x1)
y-10 = 1/4(x+10)
y-10 = 1/4x +10/4
(×4)
4y-40=x+10
4y=x+50
x-4y+50=0
B maybe or A
Because 15 percent of 212 is 31.8 so it’s closer to 40 maybe
Answer:
A
Step-by-step explanation:
π=3.14159...
Full circle are 25π cm² = 25*3.14=78.5 cm²
Half 78.5 cm²/2 = 39.25 cm²
