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 man
fiasKO [112]

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
