Michael made two trips to the market. On his first trip to the market, he bought x apples on sale for $3 each and y bananas for $2 each and spent a total of $32. On his second trip to the store, he bought x full price, apples for $5 each
and returned the y bananas he bought on the first trip. He was refunded the money for the bananas and still spent $32.

He bought 8 Apples and 4 banana

Step-by-step explanation:

Linear Combination (add equations)

So 8 Apples (X)

the put 8 in for X in either equation

4 Bananas

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
