Linda had been collecting stamps for 5 weeks and had 25 stamps in her stamp book. Her book holds 64 stamps. She then began purchasing 3 stamps each week. What was the total number of weeks that it took Linda to fill her stamp book? weeks

OpenStudy (kyanthedoodle):

13 weeks.

OpenStudy (anonymous):

how'd you get that?

OpenStudy (anonymous):

it is 13 because the remaining number of stamps she needs to collect is 64 - 25 = 39 and if she collects 3 stamps per week that is 39/3 = 13
