Question

Over the last three evenings, James received a total of 90 phone calls at the call center. The second evening, he received 2 times as many calls as the third evening. The first evening, he received 6 more calls than the third evening. How many phone calls did she receive each evening?

Answer 1

first evening = 27 calls

second evening = 42 calls

third evening = 21 calls

Explanation:

Total of 90 calls

f = first evening

s = second evening

t = third evening

Solve:

f=t+6

s = 2t

t=t

f+s+t=90

t+6 + 2t + t

(2t+t+t)+6 = 90

4t+6 = 90

4t=84

t=21

ANSWER:

f=t+6

=21+6

= 27

s = 2t

= 42

t = t

= 21
