-3x+20=2
move +20 to the other side
sign changes from +20 to -20
-3x+20-20= 2-20
-3x= 2-20
-3x= -18
divide both sides by -3
to get +x and x by itself
-3x/-3= -18/-3
Answer:
x= 6
H = hour
A = 60 + (25h) = ?
B = 120 + (20h) = ?
60 hours because 28 hours for company A x 25 dollars = 700 + starting fee is 60
28 x 25 = 700 + 60 = 760
32 hours for company B x 20 dollars = 640 + starting fee is 120
32 x 20 = 640 + 120 = 760
32 hours + 28 hours = 60 hours all together. It takes 60 hours cost the same
A= 25 x 7 + 60 = 235
25 x 7 = 175 + 60 = 235
B = 20 x 7 + 120 = 260
20 x 7 = 140 + 120 = 260
235 < 260
The cheaper one is A with 235
