Leila is buying a dinosaur model. The price of the model is xxx dollars, and she also has to pay a 7\%7%7, percent tax.
svlad2 [7]

Answer:

Leila is buying a dinosaur model. The price of the model is xxx dollars, and she also has to pay a 7\%7%7, percent tax.

Which of the following expressions could represent how much Leila pays in total for the model?

Step-by-step explanation:

The original price of the dinosaur model is "x" dollars

On top of that, the sales tax is 7% of the original price

Hence,

The total price would be the original amount PLUS the taxed amount

Original Amount = x

Taxed Amount = 7% of x

That is, 7% in decimal multiplied with "x".

7/100 = 0.07

0.07 * x = 0.07x

Total amount = x + 0.07x = 1.07x

The expression for total amount is 1.07x

A=90 degrees divide by 5
=18 degrees
2c+a=90
2c+18=90
2c=90-18
2c=72
divide each side by 2
c=36
therefore:
2c=72

b=4a+c
b=4(18)+36
b=72+36
b=108
