Answer:

6%

Step-by-step explanation:

So, lets first go over what we know:

S(Stacia) = 5(feet) when she was 12

S = 5.3 when she was 13

To find the answer, we must find the percentage of change from 5 to 5.3.

The equation we can use to find the percentage of increase looks like:

[tex]\frac{5.3}{5} = percent[/tex]

Put this in your calculator, or do this out.

When your done, you should get 1.06

Now, to put this in percentage form, we must multiply by 100:

1.06 · 100 = 106

Stacia was already 100% of her height, so the increase was 6%.

Hope this helps! :D

Answer:

5%

Step-by-step explanation:

Initial height = 5 feet

Increased height on 13th birthday = 3 inches

5 feet = 12 inches per feet = 60 inches

60 + 3 = 63 inches

[tex]\frac{4.8\times63}{100}[/tex]

[tex]4.8 \times 63=302.4[/tex]

[tex]302.4 \div100=3.024[/tex]

4.8 rounded to 5%

[tex]\frac{63-60}{60} \times 100=5[/tex]

= 5% increase

Hope this helps.
