Answer:
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
Answer:
5 months, $350
Step-by-step explanation:
Under option 1, where Tina starts with $300 and adds $10 per month, her savings after m months will be ...
300 +10m
Under option 2, where Tina starts with $200 and adds $30 per month, her savings after m months will be ...
200 +30m
__
We want to find the value of m such that the two options produce the same result:
300 +10m = 200 +30m
100 = 20m . . . . . . . . . . . add -10m-200 to both sides of the equation
5 = m . . . . . . . . . . . divide by 20
Her savings balance after 5 months will be ...
300 +10(5) = 300 +50 = 350
After 5 months, Tina will save $350 with either option.
