answer, will mark brainliest : )
daniel has $500 in his school lunch account at the beginning of the school year.
by the end of the year he needs at least $100 in the account to roll into the next school year. each week during the school year, he spends $15 on lunches. write an inequality that represents the amount of money that daniel will have to have in his account.

100>=500-15x

Step-by-step explanation:

He needs at least 100, so it's greater than OR equal to 100. He starts with 500 and goes down 15 each week. The x stands for the amount of weeks that are in the school year. Sorry for the terrible formatting on the greater than or equal to.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
