Answer:
$342.7
Step-by-step explanation:
Let the sale price be x.
So,
x - 30% of x = $239.89
x - 30/100*x = 239.89
(100x-30x)/100 = 239.89
70x = 239.89 *100
x = 23989/70
x = $342.7
sale price = $342.7
Answer:
342.70
Step-by-step explanation:
Since 100%-30%=70% our equation will be:
0.70x=239.89
x=original price
0.70x=239.89
/0.70 /0.70
Divide both sides by 0.70
x=342.7
$342.70
