15%=.15
84 x .15=$12.60 discount
subtract from $84
84-12.60= $71.40
multiply by .07 sales tax
71.40 x .07= 4.998 rounded off to $5.00
total cost $71.40 + $5.00=
$76.40 is what Tami paid for the coat
hope this helps
Answer:
2739
Step-by-step explanation:
3000-(52+276:8)-(1750:10)
3000-(52+34)-175
3000-86-175=2739
Given the Y intercept is 1, we can immediately plot (0,1).
The next points are (2,3), (6,5), (-4, -1), and (-8, -3)
Answer: Choice C. an = 8 + 9(n-1)
===========================================
Work Shown:
a1 = 8 is the first term
a7 = 62 is the seventh term
an = a1+d(n-1) = nth term of arithmetic sequence
a7 = a1+d(7-1) ... plug in n = 7; solve for d
62 = 8+d(6)
62 = 6d+8
6d+8 = 62
6d = 62-8
6d = 54
d = 54/6
d = 9 is the common difference
an = a1 + d(n-1)
an = 8 + 9(n-1) is the nth term of this arithmetic sequence
