Sagot :
Answer:
4 hours
Step-by-step explanation:
you take 42-10 because you take the total you made minus the $10 you chare to go to the house
then you take 32 divided by 8 for each hour spent
= 4 hours spent raking
If he earned $42 he spent 4 hours raking the leaves
During a fall he charges $10 to go to a house and rake the leaves and an additional $8 for every hour that he rakes the yard.
Therefore, the equation can be represented as follows;
Linear equation
- y = 8x + 10
where
x = number of hours
y = total charges
Therefore, If he earn $42 the number of hours worked can be calculated as follows:
- 42 = 8x + 10
8x = 42 - 10
8x = 32
x = 32 / 8
x = 4
Therefore, he works 4 hours to earn a total of $42
