Please help !! write an expression that can be used to determine the total change

y = 125x + 775

Step-by-step explanation:

you can make coordinate points (x, y) from the graph

x = Number of hours

y = Total Charge

(1, 800) and (2, 925)

slope from 2 points = y2-y1/x2-x1

x1 = 1

y1 = 800

x2 = 2

y2 = 925

925 - 800/2-1 = 125/1

m = 125

using y = mx + b, where m = 125,  and 1 of the coordinate points you can find the y intercept

multiply 125 times 2

925 = 250 + b

subtract 250 from both sides

b = 675

y = 125x + 675

step-by-step explanation:

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
