Applying data from the problem gives us:

In 10 years she'll have approximately $21865.4 in her account.
If <em>X</em> - <em>A</em> = <em>B</em>, then <em>X</em> = <em>A</em> + <em>B</em>. So

Answer:
x = 91.5
Step-by-step explanation:
for 30.5 miles travelled gas used is 1 gallon ← unit rate
To calculate distance travelled multiply gas used by 30.5
For 3 gallons used
distance travelled = 3 × 30.5 = 91.5 miles
⇒ x = 91.5
0.3×8=2.4
1.5×3=4.5
(2.4+4.5)+36=42.9
