DENIUS [597]

The simple interest is calculated as :

S.I = P*T*R

where S.I is the simple interest to be calculated

P = Principal

T = Time period in years

R = Annual interest rate

The the above problem,

Amount borrowed which would be the principal (P) = $400

Time period = 6 months = 1/2 year

Annual interest rate = 6.8% = 6.8/100 = 0.068

Simple Interest = P*T*R

Simple Interest = 400*1/2*0.068 = 200 *0.068

Simple Interest = $13.6

The simple interest amount that Miguel must pay to Julio at the end of six months is $13.6

Fill in the other coordinate for the line 2x−5y=11 (4, )

So you have -5y= 11 - 2x

                      y = -11/5 + 2/5x

therefore when x = 4 , y = -3/5
