lara [203]3 years ago
5 0

Step-by-step explanation:

here,

x1= -5. x2=4

y1= -22. y2=r

slope(m)=3

now we have,

m=(y2-y1)/(x2-x1)

or,3=(r-(-22))/(4-(-5))

or,3=(r+22)/(4+5)

or,3=(r+22)/9

or,27=r+22

or,r=27-22

or,r=5

Greg borrows $1975 at a simple interest rate of 5% for 3 years. Linda borrows $1975 at a simple interest rate of 4.5% for years.
weqwewe [10]

Answer:

Greg pays more interest than Linda

He pays $17.45 more

Step-by-step explanation:

Greg

P=$1975

R=5%=0.05

T=3 years

Simple interest=P×R×T

=$1975×0.05×3

=$296.25

Linda

P=$1975

r=4.5%=0.045

n=1

t=3

Linda's Interest is compounded once per period, so we this formula

Compound Interest =P(1+r)^t

=$1975(1+0.045)^3

=$1975(1.045)^3

=$1975(1.141166125)

=$2,253.80

Interest paid=$2,253.80-$1975

=$278.8
