Answer:
A = $13,660.81
Step-by-step explanation:
P (principal) = $4,800.00
I (interest) = $8,860.81
First, convert R as a percent to r as a decimal
r = R/100
r = 6.2/100
r = 0.062 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 4,800.00(1 + 0.062/4)(4)(17)
A = 4,800.00(1 + 0.0155)(68)
A = $13,660.81
-12 + 18 = 70 - 64 or(-12+18)+(6*12)-2
Since the two equations equal y, set them equal to each other.
x-1=-2x+5
From there, solve for x.
First get x on one side, by using the addition property of equality.
x-1=-2x+5
3x-1=5
Isolate x by adding 1.
3x=6
Lastly get x all by itself by dividing each side by 3.
x=2
You can now substitute your x-value, 2, into one of the equations (or both, if you wish; either one will result in the same answer.)
y=x-1
y=2-1
y=1
OR
y=-2x+5
y=-2(2)+5
y=-4+5
y=1
Final answer:
x=2 and y=1

Marc has walked 42 % of the journey
<h3>How to calculate the percentage ? </h3>
The total miles is 50 meters
Marc has walked for 21 meters
The percentage he has walked can be calculated as follows
= 21/50 × 100
= 0.42 × 100
= 42
Hence the percentage of mile Marc walked is 42%
