Problema Solution
The business Club's thrice-yearly car wash serviced 398 cars this year. A total of 84 more cars participated in May than in November. A total of 43 fewer cars were washed in July than in November. How many cars were washed during each month?
Answer provided by our tutors
The business only does the car wash three times a year (May, July, and November). Using 'm', 'j', and 'n' to stand for the number of cars washed during May, July, and November respectively, we can write:
m+j+n=398
m=n+84
j=n-43
Using Algebrator to solve for 'j', 'm', and 'n', we get:
j=76
m=203
n=119
