Answer:
- the total value after 6 years is $134.01
- Tyler has earned $34.01 in interest
- The new balance is 1.05 times the previous balance. An exponential function can provide a suitable shortcut.
Step-by-step explanation:
The worksheet you show tells you exactly how to do the calculations and where to put the numbers. For such repetitive calculations a spreadsheet is a very useful tool.
Each new balance is the previous balance multiplied by 1.05. Repetitive multiplication is signified using an exponent. For multiplication by 1.05 six times, the multiplying factor can be 1.05^6.
We need to get the variable on one side (usually the left side) and all other constants (like numbers and certain symbols like 
) on the opposite side of the variable (usually the right side).
4(2s - 1) = 7s + 12 // Our starting equation
8s - 4 = 7s + 12 // Distribute the 4 across the 2s and the -1
s - 4 = 12 // Subtract both sides by 7s
s = 16 // Add both sides by 4
The variable s is equal to 16.
4(2s - 1) = 7s + 12 // Our starting equation
8s - 4 = 7s + 12 // Distribute the 4 across the 2s and the -1
s - 4 = 12 // Subtract both sides by 7s
s = 16 // Add both sides by 4
The variable s is equal to 16.
