Answer:
21.6 $ / h
Step-by-step explanation:
Since it is a raise you'll calculate by multiplying the $ / h by (1 + % / 100)
In this case 1 + % / 100 = 1 + 20 / 100 = 1 + 0.20 = 1.20
1.20 * 18 = 21.6 $ / h
NB.:
If it was a decrease by 20 % => 1 - 20 / 100 = 1 - 0.20 = 0.80
You would multiply the $ by 0.80.
Answer:
About 182 cartons will be filled in 6.5 hours.
Step-by-step explanation:
Multiply 6.5 by 28 to get 182
Use PEMDAS
20 * 20/5 + 100 - 50
Multiply and divide first
20 * 20 = 400
400/5 = 80
Add 100 and then subtract 50
80 + 100 = 180
180 - 50 = 130
130 is the answer.
