Veronika [31]
Question: An aquarium is on sale for $59.50. If this price represents a 15% discount from the original price, what is the original price?

59.50+8.92=$68.43

Answer:

$68.43 (when rounded to the nearest cent)
or
$68 (when rounded to the nearest dollar)
or
$70 (when rounded to the nearest ten dollar)

10% of 65
Of means multiply

=6.5

Or you can use another way which is (part/whole) *(percent/100)

Whole=65
Percent=10
And part(part of 65)=unknown

(X/65)* (10/100)
Cross multiply
x= 6.5
