Answer:
A greater percentage of blue T-shirts were sold.
see the explanation
Step-by-step explanation:
we know that
To find out the percentage sold, divide the number of shirts sold by the total number of shirts and multiply by 100
so
<em>White t-shirts</em>
total shirts 200
shirts sold 120
<em>Blue t-shirts</em>
total shirts 300
shirts sold 240
Compare
therefore
A greater percentage of blue T-shirts were sold.
Given:
Number of $2 increase in price Revenue
1 1045
3 1105
5 1125
7 1105
9 1045
Plot these values in an x-y plane and observe the trend. From the illustration, locate the vertex. The vertex of the parabola is (3, 1125). Therefore, the y value of the vertex is 1125.
Without the tip it was $60. If you are being asked to add the tip it will be $69
