Answer:
D
Step-by-step explanation:
Suppose you buy the first for $30 and next for $20
The 2nd item ($20) will be given 60% discount.
<em>What is 60% of 20?</em>
<em>60/100 = 0.6 * 20 = 12</em>
<em />
So, that is off for $12, final price of 2nd item would be:
20 - 12 = $8
Total Cost (WITHOUT DISCOUNT) = 30 + 20 = 50
Total Cost (with discount) = 30 + 8 = 38
What is the percentage decrease?? It will be the DIFFERENCE (50 - 38 = 12) divided by the original price (50).
Percentage Reduction = 12/50 = 0.24
0.24 In percentage is 0.24 * 100 = 24%
D is the correct answer.

9x=303
divide by 9 on both sides
x=33 2/3
Answer:
y=1/3x-5
Step-by-step explanation:
y=1/3x+b
0=1/3(15)b
0= 5+b
b=-5
Hope this helps!
