Alexi and Tony own a food truck together that serves only twoitems, street tacos and Cuban sandwiches. Some customers purchase both goodstogether; therefore, they will always produce both goods.

Alexi and Tony can sell all the street tacos and Cuban sandwiches that they are able toproduce, and will split the revenue equally.

Suppose that Alexi and Tony can sell all their street tacos for $3.50 each and all their Cuban sandwiches for $3.50 each.

If each of them worked 20 hours per week, how should they split their time between the production of street tacos and Cuban sandwiches, if they wanted to maximize their revenue (recall they split the revenue equally)?
