Answer:
a. He will need of seed to cover the entire area.
b. He will need 5 bags of seed if he uses the highest setting and 7 bags of seed if he uses the lowest setting.
Step-by-step explanation:
a. You can calculate the area of his lawn by multiplying its dimensions.
The dimensions are:
by
We can convert the mixed numbers to decimal numbers. To do this,we must divide the numerator by the denominator of the fraction and then we must add the quotient to the whole number part.
Then, these are:
Then:
He will need of seed to cover the entire area.
b. Let be "h" the number of bags of seed that he will need if he uses the highest setting.
You know that one bag of seed will cover 500 square feet if he uses the highest setting. Then:
Let be "l" the number of bags of seed that he will need if he uses the lowest setting.
You know that one bag of seed will cover 300 square feet if he uses the lowest setting. Then:
