Step-by-step explanation:
Bob needs to save at least 10 dollars to buy that book
he gets 2 dollars in allowance every day
he has 3 dollars now
in how many days will he be able to buy the book?
translation
if d=number of days
then
how much has now+how much will earn≥10
3+2d≥10
solve
minus 3 both sides
2d≥7
divide both sides by 2
d≥3.5
but wait, you can't have 3.5 days, round up becuase if round down you wil have less than $10
answer is 4 days
that is an example, just read it and don't just report it
Answer:
Ohn has paid $5730 in first 20 installments
Step-by-step explanation:
As per the question Ohn payed the first installment =$100
Next month Ohn payed the installment = 1.1×$100
Similarly subsequent installment =1.1×1.1×$100
So we can write first 20 installments as
⇒100+100×1.1+100×1.1²+100×1.1³.........+100×
And we know in geometric series
1+x²+x³+...........
= (1-
)÷(1-x)
Therefore sum of first 20 installments will be
⇒100(1+1.1²+1.1³............ =(1- )÷(1-1.1)
= 100(1-6.73)÷(-.1)
=100×5.73÷.1
= $5730
So Ohn has paid $5730
