To solve this (assuming that you mean simple interest) you need to first know the formula for exponential growth witch is S(1+(-)I)

so with all of are numbers inputed it looks something like this 800(1+.0425)

because,
S=starting amount, I=interest rate, and T=Time (amount of time that goes by)
back to the equation it would equal 1027 (rounded to the nearest dollar)

Just from the figure,
As x decreases, y approaches 0
As x increases, y increases without bound
Answer: $128
Step-by-step explanation: So first Bob earned 8 dollars. Then he started earning 10 dollars a day every week for 2 weeks. that would have been 148 dollars (plus the 8 dollars he earned in the beginning), but he took a break once a week, subtracting 20 dollars from his pay, giving him 128 dollars in total.
Let me know if this was helpful! :D
You would do 30= 2(3x-4)+2(x-1) because all the sides are equal so the answer would be 5
