Answer:
C. $97
Step-by-step explanation:
The average of his wage for all 15 days is the sum of all wages for the 15 days divided by 15.
average wage for 15 days = (sum of wages for the 15 days)/15
The amount of wages during a number of days is the product of the average wage of those days and the number of days.
First 7 days:
average wage: $87
number of days: 7
total wages in first 7 days = 7 * $87/day = $609
Last 7 days:
average wage: $92
number of days: 7
total wages in last 7 days = 7 * $92/day = $644
8th day:
wages of the 8th day is unknown, so we let x = wages of the 8th day
total wages of 15 days = (wages of first 7 days) + (wages of 8th day) + (wages of last 7 days)
total wages of 15 days = 609 + x + 644 = x + 1253
average wage for 15 days = (sum of wages for the 15 days)/15
average wage for 15 days = (x + 1253)/15
We are told the average for the 15 days is $90/day.
(x + 1253)/15 = 90
Multiply both sides by 15.
x + 1253 = 1350
Subtract 1253 from both sides.
x = 97

Answer:
There were 16 birds at the shelter on Wednesday.
Step-by-step explanation:
Number of cats and birds on Wednesday = 34
let the number of birds on Wednesday = b
Then number of cats = (34 -b)
The rate of taking care of each bird in shelter = $3
The rate of taking care of each cat in shelter = $7
Total amount spent by shelter on Wednesday = $174
So, according to the question
b x ($3) + (34 -b) ($7) = $ 174
or, 3b + 238 - 7b = 174
or, 4b = 64
⇒ b = 64/4 = 16
Hence, the number of birds in shelter on Wednesday = b = 16
and Number of cats = 34 - 16 = 18
