What is equation modelling? What is a mathematical equation and expression?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.

A mathematical equation is used to equate two expressions.

Given is Dylan who has $14.00 to spend at the book fair. He decides to buy two paperbacks for $4.50 each.

Assume that he can spent $[x] on stickers. So, we can write -

[x] = 14 - (2 x 4.5)

[x] = 14 - 9

[x] = 5

Therefore, he can spend a maximum of $5 on sticker books.

Answer 2

Answer:
The words "at most" mean less than or equal to, which sets up an inequality using the symbol ≤.

Price of 2 books + sticker book≤$14.00.
2(4.50) + x ≤ 14.00
9 + x ≤ 14
x≤5

At most, Dylan can spend $5.00 on a sticker book.

Hope I helped, have a great day!

Answers

Let's turn them in to fractions.

$0.6\quad 0.39\quad 0.07\quad 0.8\quad 0.69\quad 0.17\n \n 0.6=\quad \frac { 6 }{ 10 } =\frac { 60 }{ 100 } \n \n 0.39=\frac { 39 }{ 100 } \n \n 0.07=\frac { 7 }{ 100 } \n \n 0.8=\frac { 8 }{ 10 } =\frac { 80 }{ 100 } \n \n 0.69=\frac { 69 }{ 100 } \n \n 0.17=\frac { 17 }{ 100 }$

$\frac { 60 }{ 100 } \quad ,\quad \frac { 39 }{ 100 } \quad ,\quad \frac { 7 }{ 100 } \quad ,\quad \frac { 80 }{ 100 } \quad ,\quad \frac { 69 }{ 100 } \quad ,\quad \frac { 17 }{ 100 } \n \n \frac { 80 }{ 100 } >\frac { 69 }{ 100 } >\frac { 60 }{ 100 } >\frac { 39 }{ 100 } >\frac { 17 }{ 100 } >\frac { 7 }{ 100 }$

Ann works in a supermarket for $10.00 per hour. If her pay is increased to $12.00, then what is her percent increase in pay ?

Answers

The percentage is the change with respect to the original thus the percentage increase in her pay will be 20%.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicatinghundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Originalamount = $10

Increased pay = $12

% increase = (12 - 10)/10 x 100

⇒ 20%

Hence "The percentage is the change with respect to the original thus the percentage increase in her pay will be 20%".
