Question

At a certain school, the ratio of the number of Brand x computers to the number of Brand Y computers is 7 to 2 . If the school has 40 Brand Y computers, what is the total number of Brand x and Brand Y computers that the school has?

Answer 1

The school has a ratio of 7 Brand x computers to 2 Brand Y computers. With 40 Brand Y computers, the school has a total of 180 Brand x and Brand Y computers.

Step-by-step explanation:

The ratio of the number of Brand x computers to the number of Brand Y computers is given as 7 to 2. If the school has 40 Brand Y computers, we can find the number of Brand x computers using the ratio.

1. First, we need to calculate the ratio factor. The ratio of Brand x to Brand Y is 7 to 2, which means for every 7 Brand x computers, there are 2 Brand Y computers. So, the ratio factor is 7/2 = 3.5.
2. To find the number of Brand x computers, multiply the number of Brand Y computers by the ratio factor. In this case, the school has 40 Brand Y computers, so the number of Brand x computers is 40 x 3.5 = 140.

Therefore, the total number of Brand x and Brand Y computers that the school has is 140 + 40 = 180.
