Question

In country​ A, about three times as many cars are manufactured per day than in country B. If the total number of these cars manufactured per day is 26 comma 416​, find the number manufactured in country B and the number manufactured in country A.

Answer 1

country a = 19,812 cars

country b = 6,604 cars

Explanation:

a = country a

b = country b

the 2 eqations are:

a + b = 26,416

a = 3b

now substitute 3b for a in the first equation:

3b + b = 26,416

add the variables:

4b = 26,416

now divide 26,416 by 4 (26,416/4)

b = 6,604

so country b has 6,604 cars

to find country b, substitute the number of cars in country b (which is 6,604) in the second equation:

a = 3b

a = 3 × 6,604

a = 19,812

so country a has 19,812 cars
