Answer:
21 pencils
Step-by-step explanation:
b 21 pencils
Let
I1-------------> interest first day
I2-------------> interest second day
we know that
P0=$73000----------> initial amount
first day
I1=73000*(5%/100)*(1/365)-----------> I1=$10
P1=P0+I1------> $73000+$10-------- P1=$73010
second day
P1=$73010
I2=73010*(5%/100)*(1/365)-----------> I2=$10
P2=P1+I2------> $73010+$10-------- P2=$73020
the answer is $73020
S = p/(q +p -pq)
q +p -pq = p/s
q -pq = p/s - p
q(1-p) = p/s - p
q = (p/s - p) / (1-p)
6x-12 = 2x-6
get like terms on the same side by adding/subtracting.
6x - 12 = 2x - 6
+ 12, -2x on both sides
6x - 2x = -6 + 12
4x = 6
divide all by 4
x = 1.5
to check your answer, plug in 1.5 for x and see if they are equal to one another.
6(1.5) - 12 = -3
2(1.5) - 6 = -3
a) fraction notation 1/5 and percent notation is 20% or just 20
b) 1/5
