Tonya grew 2.25 more inches before her 9 year height was recorded. What is her height at age 9

written with the correct number of significant digits?

Tanya's height at age of 9 is 53.75 inches

Step-by-step explanation:

Tonya's age (yr.)     Tonya's height (in.)

3                                        36.8

4                                         40

5                                       41.25

6                                        45

7                                        48.0

8                                       51.5

Tanya's height at the age of 8 = 51.5

We are given that Tonya grew 2.25 more inches before her 9 year height was recorded.

So, Tanya's height at age of 9 = 51.5+2.25

Tanya's height at age of 9 =53.75 inches

Hence Tanya's height at age of 9 is 53.75 inches
