Answer:
$8.75 is your answer.
Step-by-step explanation:
What you do is you multiply 1.25 by 7.
<em>1.25 x 7 = $8.75</em>
$8.75 is your answer.
After 45 minutes you will have painted 4*45=180 square feet.
so the total number of painted area, y, is:
y=180+x*(3+4) after the 45 minutes
where x is the number of minutes AFTER THE 45 minutes:
if y is 1000 then
1000=180+x*7
820=x*7
x=117.14
so 117 minutes, or one hour and 57 minutes.
