Pretty sure it’s B but I don’t rlly know
Answer:
If this is the way I was taught and how I took the question. 38/57 or 2/3
Step-by-step explanation:
19 * 2 = 38/
19* 3 = 57
38 ÷19 = 2/
57 ÷19 =3
so 2/3
$45 per plumber hour (p)
$25 per assistant hour (a)
$4035 = 25a + 45p
p = 2a
4035 = 25a + 45(2a)
4035 = 25a + 90a
4035 = 115a
a = 35.086 hours
p = 2(35.086)
p = 70.174 hours
The plumber worked about 70 hours, and his assistant worked about 35 hours.
