Answer:
A. 
B. 25% discount
Step-by-step explanation:
PART A:
For the shirt:
Sale price of the shirt=$18
Cost of the shirt=$24
Now, 
⇒
For the pair of shoes:
Sale price of the pair of shoes=$42
Cost of the pair of shoes=$56
Now, 
⇒
So, the equation that represents the sale price y of an item that costs x dollars is:
PART B:
y=Sale price of an item
x=Cost of the item
Discount on the item 
Percentage discount on the item

%
Answer:
B.64
Step-by-step explanation:
75% of a number is 120.
Let's take "x" be the number.
75% of x = 120
75/100 * x = 120
0.75x = 120
x = 120/0.75
x = 160
So the number is 160.
Now we have to find the 40% of the number 160.
= 40/100 * 160
= 0.4 *160
= 64
40% of the number is B.64
Thank you.
Answer:
c 17
Step-by-step explanation:
You make 23 a day plus 3.60 per sale
Income = 23+ 3.6 s
You want to make at least 84
84 ≤ 23+ 3.6 s
Subtract 23 from each side
84 -23 ≤ 23-23 +3.6s
61 ≤ 3.6s
Divide by 3.6 on each side
61/3.6 ≤ 3.6s/3.6
16.94444 ≤ s
You must make more than 16.94444 sales
But you cannot make part of a sale so
You must make at least 17 sales

<span>Kate had a test and one of the questions were 8 dived by 2 +( 6+7)+3. She answered by saying it was 13.625 . When the teacher graded it she marked it wrong then handed it to Kate saw that it was wrong. She wondered why so she asked the teacher and said why she got it wrong and explained that the parenthesis are show that you need to solve the number in it first before you do anything else. Then Kate tried to solve it again and got 20.
