<u>Answer</u>
c. buying it at a 10 percent discount without sales tax.
<u>Explanation</u>
We are going to compare the 3 choices and then determine the most cost effective.
<em>a. using a paid membership card to buy it at a 10 percent discount.</em>
10% of $100 = 10/100×100 = $10
cost = $100 - $10 = $90
On top of this $90 there is the charges of the membership card.
<em> b. buying it online at a 10 percent discount with a $5 shipping charge.</em>
100%-10% = 90%
90% of 100 = $90
Cost: $90 + $5 = $95
<em>c. buying it at a 10 percent discount without sales tax.</em>
100% - 10% = 90%
90/100 × 100 = $90. This is the must cost effective method since there is no other cost involved.
8r + 206 + 7r +79 = 360
15r + 285 = 360
15r = 75
r = 5
7(5) + 79
35 + 79
angle YMB is 114°
Answer:
Step-by-step explanation:
Given the equation:
1/5 × (x - 2) = 20
First step to solving the equation is
By multiplying both sides by the value of 5.
That will give,
x - 2 = 100
x = 100 + 2
= 102
For x=1: -7 x 1 + 4 = -3 y=-3
The ordered pair:(1, -3)
for x=3: -7 x 3 + 4 = -17 y=-17
The ordered pair:(3, -17)
for x=5: -7 x 5 + 4 = -35 y=-35
The ordered pair:(5, -35)
for x=7: -7 x 7 + 4 = -45 y =-45
The ordered pair:(7, -45)
