Answer:
Step-by-step explanation:
5p + 2(p + 4) .......because pencil cases (p) sell for 5 bucks a piece....and mechanical pencils (p + 4), sell for 2 bucks a piece. She is basically selling 4 more mechanical pencils then she is pencil cases.
$60 -$45= $15
$15/ $60* 100%= 25%
The percent discount is 25%~
It is equivalent to 23/99 but not for the rest.
As the denominator gets larger, the decimals gets smaller.
eg. 23/999 = 0.023232323...
As you can see , it is 0.02 now so it is not equivalent to 0.232323 as it is 0.2
