Final answer:
Ford Motor Company makes 25 blue cars for every 15 white cars, following the ratio of 5 blue cars for every 3 white cars.
Step-by-step explanation:
The student asks about the proportion of blue to white cars manufactured by the Ford Motor Company. Since Ford makes 5 blue cars for every 3 white cars, we can set up a ratio to find the answer. If 15 white cars are made, we use the equivalent ratio 5/3 = x/15, where 'x' represents the number of blue cars. To solve for 'x', cross-multiply and divide: (5 * 15) / 3 = x, which simplifies to 75/3 = 25. Therefore, Ford will make 25 blue cars if they make 15 white cars in one day.
