Studdy Solution

STEP 1

1. Jamal bought a total of 50 50 water balloons.
2. Jamal used 35 35 of these water balloons.
3. We need to find the percentage of water balloons used.

STEP 2

1. Define the percentage formula.
2. Substitute the known values into the formula.
3. Calculate the percentage.

STEP 3

The formula to calculate the percentage of water balloons used is:
Percentage used=(Number of balloons usedTotal number of balloons)×100\text{Percentage used} = \left( \frac{\text{Number of balloons used}}{\text{Total number of balloons}} \right) \times 100

STEP 4

Substitute the known values into the formula:
Percentage used=(3550)×100\text{Percentage used} = \left( \frac{35}{50} \right) \times 100

STEP 5

Calculate the percentage:
Percentage used=(3550)×100=0.7×100=70\text{Percentage used} = \left( \frac{35}{50} \right) \times 100 = 0.7 \times 100 = 70
The percentage of water balloons Jamal used is:
70%\boxed{70\%}
