The formula for the total amount costumers pay is 20x+20 because 20* the number of days is 20x and then you have to add the 20 dollars for the service fee. The costumer paid less than 80 dollars so 20x+20, which is what the costumer paid, is less than 80. The answer is $20x+$20<$80.

Answer:
Step-by-step explanation was 34
Answer: a= 16
Step-by-step explanation:
We have the following expression:
To find the value of the coefficient "a" you must use the distributive property to multiply the expression:
until you transform it to the form:
Then we have
Therefore the value of a in the polynomial is 16
A 30 hours per year
B 30X(100+20)%=36 per year
1.5 year later is 5.5 years
5.5X36=198 hours
