Solution: Let x be the amount to be invested (15%).
Then,
x*0.15 + 550*0.11 = (x+550)*0.12
x*0.15 - x*0.12 = 550*0.12 - 550*0.11
0.03x = 550*(0.12-0.11)
0.03x = 550*0.01
0.03x = 5.5
x =5.5÷0.03
x=183.33
Answer: $183.33 more to be invested for 12 % total return.
Answer:
x = 2
Step-by-step explanation:
At the point of intersection f(x) = g(x), thus
10x - 6 = x + 12 ( subtract x from both sides )
9x - 6 = 12 ( add 6 to both sides )
9x = 18 ( divide both sides by 9 )\
x = 2 ← at point of intersection
Answer:
D. -3.3
Step-by-step explanation:
=> 2.8x = -9.24
=> x = -9.24/2.8
=> x = -3.3
