Answer:
$180
Step-by-step explanation:
Since the cost of the telescope with the 30% discount is $126 then $126 is 70% of the original price. Remember 100-30=70. To find the original price set up a proportion with these values:
[tex]\frac{126}{x}=\frac{70}{100}[/tex]
Solve for the original price by cross multiplying numerator with denominator.
x(70) = 126(100)
70x = 12600
x= $180
Answer:
$163.8
Step-by-step explanation:
We need to first make the 30% into a decimal. So it will be 0.30.
Then you need to multiply the 0.30 into 126 { 126 x 0.30 }
Which gives you 37.8
Then to fin the original you will need to add the $37.8 to $126
Which is $163.8
Since the discount price was $37.8 and they deducted that from the original price which gave you $126 the question said.
Check : $126 + $37.8 = $163.8
