Question

Jamie and Chris both started a stamp collection at the same time. Jamie started her stamp collection with 100 stamps and added 13 stamps to her collection each week. Chris started his stamp collection with 130 stamps and added 8 stamps to his collection each week. After how many weeks did Jamie and Chris have the same number of stamps in their collections?

a.) 6
b.) 230
c.) 10
d.) 178

Answer 1

A) 6

Explanation:

8 (6) = 48

130 + 48 = 178

13 (6) = 78

100 + 78 = 178

178 = 178
