Answer:
He must bring in 40 or more customers.
Step-by-step explanation:
Let x represent the number of customers that he brings in.
He is paid $100 per week plus $5 for every customer he brings in. This means that if he brings in x customers in a week, the expression for the total amount that he would make is
100 + 5x
If he wants to make $300 or more this week, the expression would be
100 + 5x ≥ 300
5x ≥ 300 - 100
5x ≥ 200
x ≥ 200/5
x ≥ 40
He doesn't deliver any newspapers means x=0, so <span>y = 30x0 + 18=18
the answer is 18 cents</span>
7x + 5y = 19
<u>-7x - 2y = -16</u>
<u>3y</u> = <u>3</u>
3 3
y = 1
7x + 5y = 19
7x + 5(1) = 19
7x + 5 = 19
<u> -5 - 5</u>
<u>7x</u> = <u>14</u>
7 7
x = 2
(x, y) = (2, 1)
The method would be a elimination method (the answer is C).
