Answer:
<em><u>9 months</u></em>
Step-by-step explanation:
1. write out equation
100 + 22x = 298
2. Subtract 100 from both sides
22x = 198
3. Divide 22 from each side
198/22 = 9

Answer I think that it is x times 1 times 100= altitude.
Step-by-step explanation:
400/2= 200
but if you do it 700/6
it doesn't make sense unless
2 x 1 =2
2 x 100+200
The geometric mean would be 37.9
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.
