Answer 2

1)

c=(107.5/100)(79.95+2(19.99))

c=1.075(79.95+39.98)

c=1.075(119.93)

c=128.92475

c≈$128.92  (to nearest cent)

2)

w=1700(10.5/100)

w=$178.50

3)

m=1700(1.25/100)

m=$21.25

4)

ss=1700(5.7/100)

ss=$96.90

5)

I=175(.035)*5+175(.035)*4+175(.035)3...

I=175(.035)(5+4+3+2+1)

I=175(.035)(15)

I≈$91.89  to nearest cent

6)

I=Pr^t-P

I=500(104.2/100)^7-500

I=500(1.042^7-1)

I≈$167.00 to nearest dollar

7)

A=(50+11*0.89)/11≈$5.44 per lb

B=(57+11*0.49)/11≈$5.67 per lb

C=(60-5)/11=$5.00 per lb

D=(58*(100-10)/100)/11≈$4.75 per lb

So D is the best deal at just $4.75 per lb.
