Jacob bought 7 shirts for $32.90. Kyle bought 12 shirts for $60.00. Jacob paid per shirt. (32.90 ÷ 7)

Kyle paid per shirt (60 ÷ 12)

Kyle says that he paid less per shirt than Jacob. Is Kyle correct? Explain your answer.

Answer in complete sentences.

Jacob paid $4.7 per shirt.

Kyle paid $5 per shirt.

Kyle is not correct because as we can see Jacob paid 3 cents less.

Step-by-step explanation:

Jacob:

$32.90 ÷ 7 = $4.70 per shirt.

$4.70 per shirt.

Jacob paid $4.70 per shirt. (32.90 ÷ 7)

Kyle:

$60 ÷ 12 = $5 per shirt.

$5 per shirt

Kyle paid $5 per shirt (60 ÷ 12)

Kyle says that he paid less per shirt than Jacob. Is Kyle correct? Explain your answer.

Kyle is incorrect. $5 is more than $4.70.  

$5 - $4.70 =

0.30 cent difference.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
