The average weekly number of toy cars produced by Factory T and U is 3421. The average weekly number of toy cars produced by Factory T and V is 7021. If Factory U produced ²₇ as many toy cars as Factory V each week, how many toy cars does Factory T produce weekly?
Total toy cars that Factory T and Factory U produced
= 3421 x 2
= 6842

Total toy cars that Factory T and Factory V produced
= 7021 x 2
= 14042

Number of toy cars produced by Factory U = 2 u
Number of toy cars produced by Factory V = 7 u

Factory T's toys + 2 u = 6842 --- (1)
Factory T's toys + 7 u = 14042 --- (2)

(2) - (1)
7 u - 2 u = 14042 - 6842
5 u = 7200
1 u = 7200 ÷ 5 = 1440

Number of toy cars produced by U
= 2 u
= 2 x 1440
= 2880

Number of toy cars produced by T
= 6842 - 2880
= 3962

Answer(s): 3962
