It looks like everyone's amount of money is based on Maria's amount of money. Let's say Maria is M, Hans is H and Dan is D. Maria has M amount of money. If Hans has 10 more than Maria, he has M+10. If Dan has 3 times what Hans has and Hans has (M+10), then Dan has 3(M+10) which is 3M+30. Altogether they have 95 dollars. So we will add up what they have and set it equal to 95. M+10+M+30+3M=95. That simplifies to 5M+40=95 and 5M=55. Therefore, Maria has 11 dollars. Hans has 10+11=21, and Dan has 3(21)=63. 11+21+63=95
Using an exponential function, it is found that the value of Yong's investment account after 7 years is given by:
(C) $2363
<h3>What is an exponential function?</h3>
It is modeled by:
In which:
Her account was worth $2000 initially, and it increases by 10%, percent every 4 years, hence, it is modeled by:
After 7 years, the amount is:
Hence option C is correct.

Step-by-step explanation:
Based on the percentage gas price increases across all the six energy companies, the range of gas price increases is 2.9%.
<h3>What is the range of percentage increase in gas prices?</h3>
This can be found by subtracting the lowest price increase from the highest percentage increase.
The range is:
= Highest increase - lowest increase
= 11.1 - 8.2
= 2.9%
