A lawyer spends $75.00 on 3 staplers and 3 pads of paper. If each stapler costs $21.75, and each pad of paper costs x dollars, which statement is true?

Answers

Each pad of paper cost 3.25. Here is how I found it.

21.75 x 3 = 65.25
75 - 65.25 = 9.75
9.75 / 3 = 3.25

X = 3.25

Is this what you were looking for?
If staplers cost 21.75 each and there’s 3, you would need to do 21.75x3=65.25
You have 9.75 left for pads of paper and there’s 3 so 9.75/3=3.25

Each pad of paper costs $3.25 or x=3.25

The number of customers at Yummy Smoothies varies throughout the day. During the lunch rush on Saturday, there were 120 customers at Yummy Smoothies. The number of customers at Yummy Smoothies during dinner time was 10 customers fewer than the number during breakfast. The number of customers at Yummy Smoothies during lunch was 3 times more than during breakfast. How many people were at Yummy Smoothies during breakfast? How many people were at Yummy Smoothies during dinner? Let d represent the number of customers at Yummy Smoothies during dinner and b represent the number of customers at Yummy Smoothies during breakfast.

Answers

Answer:

190 people

Step-by-step explanation:

At lunch, there were 120 people.

There were 3 times more people at lunch than breakfast meaning you divide 120 by 3.

120 / 3 = 40

At dinner, there were 10 people less than at breakfast.

40 - 10 = 30

Add up your numbers.

120 + 40 + 30 = 190

B = 40

L = 120

[tex]\sf{(1,5)}\longleftarrow\sf{new~coordinates~of~the~market}[/tex]

What was Paul's mistake?

Paul's mistake was:-

He moved the market 3 units to the left and 2 units down, when he should have moved it 2 units to the left and 3 units down.

note:-

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

Answer:

New location: (1, 5)

Paul's mistake: His mistake was that he switched moving 2 units left and 3 units down with 3 units left and 2 units down.

Step-by-step explanation:

The market was previously at (3, 8).

3 – 2 = 1 (subtract the previous market location with what he's moving with: which is 2)

8 – 3 = 5 (subtract the previous market location with what he's moving with: which is 3)
