Answer:
$75.5
Step-by-step explanation:
The first step is to calculate the percentage decrease
= 100-18
= 82%
Therefore the original cost of the shirt before the discount can be calculated as follows
= 82/100 × x = 61.91
= 82x/100= 61.91
Cross multiply
82x= 100×61.91
82x= 6191
x = 6191/82
= 75.5
Hencd the original cost of the shirt is $75.5
