Answer:
h ≤ 8
Step-by-step explanation:
Hans charges $7 per hour and pays $5 in equipment fees.
$5 is fixed in this case. Let the possible number of hours be h.
According to question,
Atleast means less than equal to. So,
7h-5≤51
Add 5 to both sides.
7h+5-5 ≤ 51+5
7h ≤ 56
h ≤ 8
So, the number of hours be less than equal to 8.
So just add equation 1 and equation 2
You will get
2x-2x + 5y + 3y = 12 + 4
8y = 16
y = 16/8
y = 2
Substituting y in equation 1
2x + 5*2 = 12
2x + 10 = 12
2x = 12 - 10
x = 2/2
x = 1
=
