Mrs. Robertson is carpeting her rectangular living room. The room is 10 feet wide and 15 feet long. What is the
area to be carpeted?

150 ft

Step-by-step explanation:

The formula for area is, height x width (h x w) or base x height (b x h)

10 feet is the base and 15 is the height, multiply those and you get 150

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.
