Answer:
12 pens
Step-by-step explanation:
Let the variable that can be used to determine the number of pens that Kamila bought be represented by n.
Price of a notebook = $1.59
Price a pen = $0.29
Total amount spent = $5.07
But,
1.59 + 0.29 n = 5.07
So that,
0.29 n = 5.07 - 1.59
0.29 n = 3.48
n = 
= 12
Therefore, Kamila bought 12 pens.
90% of 100 = 0.9 x 100 = 90
------------------------------------------------
Answer: The visitor can see 90 ships.
------------------------------------------------
$12,500 x 5% = $625.
$12,500 + $625 = $13,125.
90=6x+3x
90=9x
90/9=x
10=x
3x=3*10=30
6x=6*10=60
