Devan is a sculptor and needs to rent studio space to work. He found a great spot, but it costs $30.75 per hour. Last month he logged 82.5 hours in the studio. A donor gave him $2,500 to put toward this expense. Is it enough money? If so, how much is left? If not, how much more does he need to cover the bill? Round to the nearest cent.(1 point)
Responses
To determine if the $2,500 donation is enough to cover Devan's studio rental expense, we can calculate the cost for 82.5 hours at $30.75 per hour:
Cost = 82.5 hours * $30.75/hour
Cost = $2536.25
The cost of Devan's studio rental for 82.5 hours is $2536.25.
Since the total cost exceeds the donation amount of $2,500, Devan needs an additional amount to cover the bill. The additional amount needed is:
Additional amount needed = Cost - Donation
Additional amount needed = $2536.25 - $2500
Additional amount needed = $36.25
Therefore, Devan needs $36.25 more to cover the studio rental bill.
Charlotte is buying three large watermelons for her summer party. Watermelon costs $0.46 per pound. Charlotte weighs her watermelons and finds they weigh 19 pounds, 15.2 pounds, and 13.7 pounds. How much will she pay for the watermelons? Round to the nearest cent.(1 point)

To find out how much Charlotte will pay for the watermelons, we need to calculate the cost for each watermelon and then sum them up.
Watermelon 1:
Cost = 19 pounds * $0.46/pound
Cost = $8.74
Watermelon 2:
Cost = 15.2 pounds * $0.46/pound
Cost = $7.03
Watermelon 3:
Cost = 13.7 pounds * $0.46/pound
Cost = $6.32
Total cost = $8.74 + $7.03 + $6.32
Total cost = $22.09
Therefore, Charlotte will pay $22.09 for the three watermelons.
The area of a rectangle is solved by multiplying the length and width of a rectangle. A rectangular field has an area of 57,600 square feet. If its width is 160 feet, what is its length?(1 point)
To find the length of the rectangular field, we can use the formula for the area of a rectangle and substitute the given values:
Area = Length * Width
Given:
Area = 57,600 square feet
Width = 160 feet
Substituting the values:
57,600 = Length * 160
To solve for the length, divide both sides of the equation by 160:
57,600 / 160 = Length
Length = 360
Therefore, the length of the rectangular field is 360 feet.
Donnie and Ronnie are trying to figure out how much they weigh in kilograms. They discover that 1 kilogram equals 2.2 pounds. Donnie weighs 188 pounds, and Ronnie weighs 165 pounds. What is the difference in their weights in kilograms? Round to the nearest hundredth.(1 point)
To find the weight difference in kilograms between Donnie and Ronnie, we first need to convert their weights from pounds to kilograms.
Donnie's weight in kilograms:
188 pounds * (1 kilogram / 2.2 pounds) = 85.45 kilograms (rounded to the nearest hundredth)
Ronnie's weight in kilograms:
165 pounds * (1 kilogram / 2.2 pounds) = 75 kilograms (rounded to the nearest hundredth)
Now, we can find the difference in their weights in kilograms:
Difference = Donnie's weight in kilograms - Ronnie's weight in kilograms
Difference = 85.45 kilograms - 75 kilograms = 10.45 kilograms (rounded to the nearest hundredth)
Therefore, the difference in their weights in kilograms is 10.45 kilograms.
