Hello :
let A and B two points in the first line calculate the slope : <span>: (YB - YA)/(XB -XA)
</span>let C and D two points in the second line calculate the slop (YC - YD)/(XC -XD)
you are slope
This is the concept of financial mathematics, the simple interest rate is given by:
S.I.=(PRT)/100
where:
P=principle=$2500
R=rate=5.5%
T=time=1 year
Hence;
S.I.=(5.5*2500.1)/100
=$137.5
Thus the total amount he had after 1 year will be:
2500+137.5
=$2,637.5
