Joy donated $53 to one charity and $99 to another. What percentage of her total donations went to the charity receiving $99?

To determine what percentage of Joy's total donations went to the charity that received $99, first calculate her total donations. She donated $53 to one charity and $99 to another.

The total amount donated is the sum of these two amounts:

[

53 + 99 = 152

]

So, Joy's total donations amount to $152.

Next, to find the percentage of her total donations that went to the charity receiving $99, use the formula for percentage:

[

\text{Percentage} = \left( \frac{\text{Amount donated to the charity}}{\text{Total donations}} \right) \times 100

]

Substituting the known values:

[

\text{Percentage} = \left( \frac{99}{152} \right) \times 100

]

Now calculate the fraction:

[

\frac{99}{152} \approx 0.651315

]

Multiplying by 100 to convert this decimal into a percentage gives:

[

0.651315 \times 100 \approx 65.13%

]

When rounding this, it is commonly rounded down to the nearest significant figure, typically to 65%.
