The number of Bryan's gold pencils and Albert's green pencils is the same.
The number of Bryan's gold pencils is repeated. The number of Albert's green pencils is repeated. Make the number of Bryan's gold pencils and Albert's green pencils the same. LCM of 1 and 4 is 5.
Number of green pencils
= 15 u + 5 u
= 20 u
20 u = 160
1 u = 160 ÷ 20 = 8
Total number of pencils
= 15 u + 5 u + 5 u + 1 u
= 26 u
= 26 x 8
= 208
Answer(s): 208
