Answer:
B
Step-by-step explanation:
essentially the plan that increases the price the most per week reaches the goal of $12 fastest.
plan A is $0.10 per week.
plan B it is not clear, if it means 10% of the original price every week, or every week 10% of the price of the previous week. I assume the first and simplest.
that means 10% of $8 = $0.80 per week.
plan C : the same amount every week until reaching $12. we need to increase in total by $4 (from $8 to $12). to reach these $4 in 8 weeks, we need to increase the price every week by 4/8 = $0.50.
plan D : $0.25 per week.
so, the plan with the highest increase every week and therefore the fastest one reaching $12 is plan B.

Answer:
8
Step-by-step explanation:
-(5 – 9) - (-2)(2)
-(-4) - (-2)(2)
4 - (-4)
4 + 4
8
Use PEMDAS
David sold 60 bottles and Sammy sold 100 bottles. x(5+3)=160; 5x+3x=160; 8x=160; 8x/8=160/8; x=20; 20(5+30); 100+60=160
Answer:
Number of terms: n=6
Step-by-step explanation:
We are given:
a₁ = 0.75
r = 4
Sₙ = 1023.75
We need to find number of terms i.e n
The formula used will be:
Putting values and fining n

We know that 

Using Exponent rule: 

So, Number of terms: n=6
