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.

Step-by-step explanation:
Let x be the length and y be the width of the rectangular plot.
The plot is bounded on one side by a river and on the other three sides by a single-strand electric fence. It means,
x+2y = 1500
x = 1500 - 2y ....(1)
We know that the area of a rectangular plot is given by :
A = xy ....(2)
Put the value of x from equation (1) in (2)
.....(3)
For largest area, differentiate above area equation wrt y.
Put the value of y in equation (1).
x = 1500-2(375)
= 750 m
Put the value of y in equation (3).
Hence, the largest area is 281250 m² and its dimensions are 750 m and 375 m.
