Kendra charges $11 to shovel a driveway. she shoveled 4 driveways on saturday and then some more on sunday. she made $143 for the weekend. how many driveways did she shovel on sunday? choose two answers: one for the equation that models this situation, and one for the correct answer.

Let number of driveways , she shoveled on Sunday = x

And for 4 driveways , Kendra charges = 4*11=44

Therefore,

143 = 44 + 11x

And that's the model for the given situation .

Subtracting 44 from both sides,

143-44 = 11x

99 = 11x

Dividing both sides by 11

x = 9

Therefore she shoveled 9 driveways on Sunday .

Kendra charges $11 to shovel a driveway .

let us say she shoveled x driveways on Sunday.

Money she made on Sunday =11x

Money she got from shoveling 4 driveways on Saturday = 11*4 =$44

total money she made on weekend = $143

11x+44 =143

11x=143-44

11x= 99

x=9

So she shoveled 9 driveways on Sunday

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.
