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: $97
A) cubic feet, a pool is too big so measure it in cubic feet
The numbers that are 0.6 unit from 1.3 on the number line are 0.7 and 1.9
<h3>How to determine the
numbers that are 0.6 unit from 1.3 on the
number line?</h3>
The number is given as:
Number = 1.3
The distance is given as:
Distance = 0.6
The numbers that are 0.6 unit from 1.3 on the number line are represented as:
Number = 1.3 ± 0.6
Expand
Number = (1.3 - 0.6, 1.3 + 0.6)
Evaluate
Number = (0.7, 1.9)
Hence, the numbers that are 0.6 unit from 1.3 on the number line are 0.7 and 1.9

Answer:
38.0
Step-by-step explanation:
38.0 to the nearest whole number
If you do 25 x X = 100
It would be x = 4
So we would divide 36% by 4 to get how many times he rode, which is 9
So he already has ridden 9 times.
