If you
Let x to be the total number of pages in a book,
then 1/3x = 117
because 117 = 1/3 of a book
Number one is correct and so is two
The exponents of expression one are the same as the exponents of expression two
$1.40 - price from a supplier = 100%
100% + 80% = 180% = 1,8 - the retail price
1,40 * 1,8 = $2,52 - the retail price
100% - 25% = 75% = 0,75 - on sale for 25% off
2,52 * 0,75 = $1,89 - the sale price.
