Answer:
240 months
Step-by-step explanation:
So, since 1 score is 20 years. Then our conversion factor would be 12 months divided by 1 year . We use the conversion factor that has a year unit in the denominator so that we can cancel the year unit.
20 years x (conversation factor) = 20 years x ( 12 months ÷ 1 year )
= 20 x 12 months
= 240 months
