The design plans for a new concert hall show elevations relative to ground level at 0 feet. The elevation of the balcony floor is 37 feet, and the elevation of the basement floor is -17 feet. How many feet above ground level is the balcony floor?

The bacony floor is 37 feet above the ground floor.

Step-by-step explanation:

Here, the ground level is marked as 0 feet.

The elevation of the balcony floor is 37 feet.

The elevation of the basement floor is -17 feet.

Since elevations relative to ground level at 0 feet.

i.e. elevation of balcony floor is same as the distance of balcony floor from ground.

That means the bacony floor is 37 feet above the ground floor.

Hence, the bacony floor is 37 feet above the ground floor.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
