P = $70, p = 2.5% = 0.025
q = 1 + 0.025 / 12 = 1.002
Future value of a periodic deposit:
A = P · q · ( q^30 - 1 ) / ( q - 1 )
A = 70 · 1.002 · ( 1.002^30 - 1 ) / ( 1.002 - 1 )
A = $2,166
Answer:
He will have $2.166 in 30 months.
Answer:
Hi there the answer will be (3,11)
Since you are using the substitution way, you first plug in one of the y's into the other equation and you can see that they are set equal to each other.
2x+5=3x+2
Then you subtract 2x on both sides to get the x's on the same side
and you get 5=x+2
Then you subtract 2 on both sides, and you get x to equal to 3
then you plug x into any equation to get y to equal 11
y= 2(3)+5
Let the speed of walking of James = x mile/hour
speed of jogging = 2x mile/hour
9/2x + 1.5/x = 2
or, (9 + 3)/2x = 2
or, 12 = 4x
or, x = 3
Average speed of walking = 3 mile/hour
Average speed of jogging = 2 * 3 = 6 mile/hour
