Answer:
The Cost Price will be $19.99
Step-by-step explanation:
James
Sale Price = (100 - Discount Rate) x Cost Price
Let Y = Cost Price
By Putting the values in above equation:
$16.99 = (100 - 15) x Y
$16.99 = 0.85Y
Dividing the equation by 0.85, we get
Y = $16.99 / 0.85
Y = $19.99
9/10 + 8/100
9/10 + 2×4/25×4
Common denominator is 50.
9/10 + 2/25.
5×9/5×10 + 2×2/2×25
45/50 + 4/50
= 49/50
