Suppose that alexi spent all 20 hours of his time on street tacos and tony spent 17 hours on cuban sandwiches and 3 hours on street tacos. combined they would produce a total of tacos and cuban sandwiches.

Given that Alexi and Tony own a food truck that serves only two items, Street tacos and Cuban sandwiches, given that Alexi can make 80 street tacos per hour but only 20 Cuban sandwiches and Tony can make 100 street tacos or 30 cuban sandwiches.

Suppose that alexi spent all 20 hours of his time on street tacos, he will make a total of 20 x 80 = 1,600 street tacos and tony spent 17 hours on cuban sandwiches and 3 hours on street tacos, he will make a total of 17 x 30 = 510 cuban sandwiches and a total of 3 x 100 = 300 street tacos.

Combined they would produce a total of 1,600 + 300 = 1,900 street tacos and 510 cuban sandwiches.
