First off, an inequality means that there is no equals sign... it will be either greater than (>) or less than (<). So we'll solve yours with the assumption that it is supposed to be greater than...

2s + 5s + 12 > 132
7s + 12 > 132
7s > 132 - 12
7s > 120
s > 120/7
s > 17 1/7

**If it was supposed to be less than instead of greater than, just change the sign. It doesn't affect the outcome.

a contractor charges $1200 for 100 square feet of roofing installed. at this rate, how much does it cost to have 1100 square fee

Ratling [72]

Step-by-step explanation:

If it cost $1200 to install 100 square feet of roofing, then it will cost $13200 to have 1100 square feet installed.

$1200/ 100 square feet multiply 11 on both sides

$13200/ 1100 square feet
