Freight car loadings over an 18-week period at a busy port are as follows:

Week	Number	Week	Number	Week	Number
1	220	7	350	13	487
2	245	8	360	14	475
3	269	9	436	15	513
4	275	10	380	16	510
5	316	11	425	17	517
6	310	12	450	18	541

Determine a linear trend line for expected freight car loadings. (Round your intermediate calculations and final answers to 3 decimal places.)

Use the trend equation to predict expected loadings for weeks 24 and 25. (Round your intermediate calculations and final answers to 3 decimal places.)

The manager intends to install new equipment when the volume exceeds 842 loadings per week. Assuming the current trend continues, the loading volume will reach that level in approximately how many more weeks? (Round your intermediate calculations to 3 decimal places and final answer to the nearest whole number.)
