Shiloh initially invested $125, which grows annually at a rate of 2.5%.

Step-by-step explanation:

The balance in the account is given by the following exponential expression,

Exponential growth formula is

Where P is the initial amount invested

r is the rate of interest

When we compare the formula with given expression , we can see that we have 125 in the place of P

So initial amount invested is $125

Now we find out 'r'

1+ r = 1.025

Subtract 1 on both sides

r= 0.025

To get percentage we multiply by 100

0.025 * 100 = 2.5%

Shiloh initially invested $125, which grows annually at a rate of 2.5%.

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
