Answer:
120 and 12
Step-by-step explanation:
115+17= 132
132/110= 1.2
1.2 · 100= 120
132-120= 12
You can find the slope of the two points with the following formula:
Substitute the corresponding values into the equation.
The slope of the line is 2.
The answers for both the parts are as (a) the rate of proofreading is 7.5 pages per hour and (b) The payment received for each page is $2,.67.
In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
The pages proofread in 2 hours is 15.
The total amount received is $40.
(a) The proofreading rate can be known by dividing the total pages by total time as below,
Rate of proofreading = 15/2 = 7.5 pages per hour.
(b) As per the question the unitary method can be applied to obtain the payment for one page as follows,
Payment for proofreading 15 pages = 40
Thus, payment for proofreading one page is 40/15 = 2.67.
Hence, the proofreadingrate is 7.5 pages per hour and the average payment for each page is $2.67 respectively.
