Robin earned $4,320 in 9 weeks. How much did he earn working for a full year?

4320/9=$480 per week.

Then you do $480 time the 50 weeks he worked for the whole year.

480

*50

24000

Robin earns $24,000 from working for the whole year (50 weeks).

feel free to report me if im wrong

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
