The value of 7 in 507264 is 10 times the value of 7 in which 493735 587921 672439 714093

Read the original number aloud 507264 notice after the seven our next word was thousand that 7 Stands for 7000. divide 7000 by 10 to get 700 we need the number that has the word 100 right after the word 7 when you say it aloud the answer is 493735

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
