A lawn mowing service charges a one-time fee of $40 and $50 per hour for leaf mulching and yard cleanup.
If you were to write this scenario as a linear equation, what is the y-intercept?
90
10
40
50

40

Step-by-step explanation:

The y intercept is the point where the x is 0. If the lawn mowing service spent 0 hours they would charge you $40

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
