1. so far, renee has commitments from fifteen people to paint the amount of square feet shown in the table below. complete the last column of the table to find the total amount of square feet that she has commitments to paint.

Explanation:

Step1: Calculate the total square feet for 2 people painting 1,600 square feet each

$2\times1600 = 3200$

Step2: Calculate the total square feet for 3 people painting 1,400 square feet each

$3\times1400=4200$

Step3: Calculate the total square feet for 2 people painting 900 square feet each

$2\times900 = 1800$

Step4: Sum up all the total square - feet values

$3200+1800 + 3200+4200+4000+1800+1600$
$=(3200+1800)+(3200+4200)+4000+(1800+1600)$
$=5000+7400+4000+3400$
$=(5000+7400)+(4000+3400)$
$=12400+7400$
$=19800$

Answer:

19800
