Steven thinks that he will spend about 70 dollars. thus it is not a reasonable amount. hence the actual total cost is $ 48.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given that steven wants gifts for his 2 little brother and 2 older sisters he plans on spending $12 dollars on each one.
But steven thinks he will spend about 70 dollars.
Which is not a reasonable amount.
It would be 4 x $12 is about 4 x $12 = 48 dollars
Therefore, the actual total cost is $ 48.
Steven thinks that he will spend about 70 dollars. thus it is not a reasonable amount.

Since NELR is a parallelogram we have RN parallel to LE.
This means <RNE and <LEN are same side interior angles and add up to 180 degrees.
So we have 7x+33+11x+21 = 180
18x = 126 . x = 7
the maximum height is the y-value of the vertex.
h(x) = -2x² + 20x + 48
<em> a=-2, b=20, c=48</em>
h(5) = -2(5)² + 20(5) + 48
= -50 + 100 + 48
= 50 + 48
= 98
