Given that Carlene needs $500 for a desk, the time taken for her to purchase the desk will be found as follows;
500=400e^(0.06t)
500/400=e^(0.06t)
1.25=e^0.06t
introducing natural logs;
ln1.25=0.06t
t=(ln1.25)/0.06
t=3.7 years
the answer is 3.7 years

Answer:
the answer is 38.81833333333333
Step-by-step explanation:
A. 3x+4/2 = 9.5
3x + 4/2 = 9.5........criss cross
3x+4= 9.5×2
3x = 19-4
3x = 15
x=5 ..........divide both sides by 3
B. 7+ 2x/3= 5.......criss cross
7+2x = 5 × 3
7 + 2x = 15
2x = 15-7
2x = 8......divide both sides by 2
x = 4
First simpliify
(3r^2+4)(2r-1)=
(3r^2+4)(2r)+(3r^2+4)(-1)=
(6r^3+8r)+(-3r^2-4)=
6r^3+8r-3r^2-4=
put back
6r^3-3r^2+8r-4-8r^3+6r^2=
-2r^3+3r^2+8r-4
