Answer: Hello, where is the question here? The analysis is correct to a large extent. Please send me the requirement. Thank you
The cost of each pizza is
We were given that, Natalia paid $38.95 for three medium sized pizzas and a salad.
represent the cost of each pizza and
be the price of a salad.
Then we can write the equation,
But we were also told that Natalia paid $11.98 for a salad. This means the cost of a salad is $11.98.
This implies that,
We now put equation (2) into equation (1) to get,
We now solve for p to obtain,
This gives us,
We divide through by 3 to get,
Therefore the cost of each pizza is $8.99.
it is a right angle! the angle formed by perpendicular lines is a 90 degree angle.
