well, 7+5=12, so he has 5 pencils, then you add 3, which gives you 15. So
Don has 15 markers
Answer:
Don have 15 markers.
Step-by-step explanation:
Don has 5 more pencils than crayons.
Let the number of crayons Don has = 7
number of pencils he has = 5 + 7 = 12
Don has 3 more markers than pencils.
Number of markers Don has = 3 + 12 = 15 markers
Don have 15 markers.
