Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>Leila is buying a dinosaur model. The price of the model is x dollars, and she also has to pay a 7%, percent tax. </em>
<em>Which of the following expressions could represent how much Leila pays in total for the model?</em>
My answer:
Given the information:
The original price of the model: x
Taxed Amount = 7% of x
<=> That is, 7% in decimal multiplied with "x"
<=> = 0.07x
=> Total amount Leila needs to pay is:
= The original price + Taxed Amount
= x + 0.07x
= 1.07x
Therefore, the expressions could represent how much Leila pays in total for the model 1.07x
Hope it will find you well.

Answer:
c = 15d + 30
Step-by-step explanation:
Hey there!
This can be represented by an equation of a line, where the number of days is our x-values(d), and the price is our y-values(c).
The price for one day ($45) and the price for 4 days($90) are specific points on that line.
The points are (1, 45) and (4, 90).
We can first find the slope of the line:
- As the price rises 45, the days increase by 3
- Slope = rise/run
- Slope = 45/3
- Slope = 15
Now we can find the base price, by plugging the slope and a point into the equation y = mx + b.
Solve for b:
- y = mx + b
- 45 = 15(1) + b
- 45 = 15 + b
- 30 = b
The base price (b) is 30.
The equation is
