RAMON SELLS CARS AND TRUCKS HE HAS ROOM ON HIS LOT FOR 521 VEHICLES. Ramon has 175 more more cars than trucks. How many of each vehicles should he have

he should have 348 cars and 173 trucks.

Step-by-step explanation:

Let x represent the number of cars that he should have.

Let y represent the number of trucks that he should have.

He has room on his lot for 521 vehicles. It means that

x + y = 521- - - - -- - - - -1

Ramon has 175 more more cars than trucks. It means that

x = y + 175

Substituting x = y + 175 into equation 1, it becomes

y + 175 + y = 521

2y = 521 - 175 = 346

y = 346/2

y = 173

x = y + 175 = 173 + 175

x = 348
