you've got a summer job renting beach umbrellas and chairs to tourists at the beach. part of your job is to encourage people to rent from you, your pay structure includes an incentive. along with a daily rate of pay of $50, you earn an extra $2 per umbrella you rent and $1 per chair you rent. you kept a tally of the number of umbrellas and chairs you rent each day. what is the function you can use to quickly calculate your earnings?

50+2x+y

Step-by-step explanation:

50 dollars plus 2dollars , x representing how many umbrellas are being rented, and y representing how many chairs are rented

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

i think the answer is b x = 1, y = 35/2
