Answer:

<u>Marcelino will have $7.50: his costs are more than his profits. </u>

Step-by-step explanation:

22.50 + 7.50 + 15.00

In total Marcelino spent $45 to make these balloons.

He wants to sell each balloon for $1.25.

If he sells the 30 balloons he bought for $1.25 he will make:

30 * 1.25 = $37.50... okay he made some money, BUT he spent $45 dollars for the items.

45 - 37.50 = $7.50, Marcelino made no profit... he still needs to make $7.50 to pay off his own costs.

After 4,000 gallons of water were added to a large water tank that was already filled to 3/4 of its capacity, the tank was then

Answer: The correct option is

(E) 80,000.

Step-by-step explanation: Given that after adding 4,000 gallons of water to a large tank that was already filled to $\dfrac{3}{4}$ of its capacity, the tank was then at $\drac{4}{5}$ of its capacity.

We are to find the number of gallons of water that the tank hold when filled to capacity.

Let the tank can hold x gallons of water when filled to capacity.

Then, according to the given information, we have

$\dfrac{3}{4}x+4000=\dfrac{4}{5}x\\\\\\\Rightarrow \dfrac{4}{5}x-\dfrac{3}{4}x=4000\\\\\\\Rightarrow \dfrac{16-15}{20}x=4000\\\\\Rightarrow x=4000\times20\\\\\Rightarrow x=80000.$
