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.

Answer:
The correct answer is 1/2 or 0.5
Step-by-step explanation:
8(15-4)/4^2-5
8(11)/4^2-5
Now i'm going to multiply 8 by 11
88/4^2-5
Now solve 4^2
Which is 16.
Now we have 88/16-5
Divide 88 and 16 which is 5.5.
Now minus 5.5 - 5 which gets us our answer: 0.5
Answer:
d c a b
Step-by-step explanation:
a=28/60
b=40/60
c=15/60
d=6/60
so d<c<a<b
