$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.

Solution
1) <span>Simplify <span><span>−5n−4n</span></span> to <span><span>−9n</span></span>
</span><span><span>−9>−9n
</span></span>
2) <span>Divide both sides by <span><span>−9</span></span>
</span><span><span>1<n
</span></span>
3) <span>Switch sides
</span><span><span>n>1</span></span>
18 - 25 = -7
11 - 18 = -7
4 - 11 = -7
The common difference is -7.
