The table compares two countries and two products. A 4-column table has 2 rows. The first column is labeled country with entries Country A, Country B. The second column is labeled Cost (units) with entries 1, 1. The third column is labeled Petroleum (units) with entries 16, 8. The fourth column is labeled Seafood (units) with entries 8, 8. What might be the best decision for Country A?

C. Focus on the petroleum industry only.

Step-by-step explanation: since Company A and Company B can produce the same amount of Seafood, Company A can produce more petroleum so they should opportunity cost by choosing to produce just petroleum.

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
