the price is 0.55$ per square foot
Step-by-step explanation:
We can solve the problem by using the rule of three.
In fact, we know that:
1 gallon covers an area of 
While the price per gallon is
$55 per gallon
This means that the price per is $55, since 1 gallon cover
Therefore, to find the price per square foot, we can write
WHere x is the price per square foot. Solving for x,
So, the price is 0.55$ per square foot.

J/4 - 8 < 4
<u> + 8 + 8 </u> *add 8 to both sides to cancel -8.
j/4 < 12
<u>*4/1 *4/1 </u> *multiply 4/1 to both sides to cancel 1/4
j < 48
j should be less than 48 to make the inequality true.
example: j = 47
j/4 - 8 < 4
47/4 - 8 < 4
11.75 - 8 < 4
3.75 < 4
Any number below 48 will end up with an answer less than 4. if j is 48 and above, the inequality is false because the answer arrived at will be equal to or greater than 4.
The only answer that makes sense to me is B.
This can be solved using a system of equations.
Subtract y from both sides.
Substitute:
Subtract 80 from both sides:
Divide both sides by 5:
Substitute.
