Question

The ratio of black marker in a box to blue markers in a box is 3:5. If there are 10 more blue markers than black markers,how many total markers are in the box.

Answer 1

Answer:

$Total = 40$

Step-by-step explanation:

Given

$Black:Blue = 3:5$

$Blue = 10 + Black$

Required

Determine the total number of markers

First, we need to determine the ratio of black to blue such that

$Blue = 10 + Black$

$Black:Blue = 3:5$

Multiply the ratio by 5

$Black:Blue = 3 * 5 : 5 * 5$

$Black:Blue = 15 : 25$

By direct comparison:

$Black = 15$

$Blue = 25$

The above shows that:

$Blue = Black + 10$

So:

$Total = Black + Blue$

$Total = 25 + 15$

$Total = 40$
