Chance has hired a construction crew to renovate his kitchen. They charge $3.89 per square foot for materials and $121.26 per da
Pepsi [2]

Answer:

The answer to your question is: letter B. 16 days

Step-by-step explanation:

Materials = $3.89 square foot

Day of labor = $121.26

Total $2982.68

Square feet = 252 more than the number of days

Process

                  materials = days of labor + 252

materials = m

days of labor = d

                             m = d + 252  (I)

Total Equation  

                         3.89m + 121.26d = 2982.68

                         3.89(d + 252) + 121.26d = 2982.68        

                         3.89d + 980.28 + 121.26d = 2982.68

                         3.89d + 121.26d = 2982.68 - 980.28

                                       125.15d = 2002.4

                                                 d = 16

Number of days 16.

that is square-kite

square=AC^2=(AE+EC)^2=(9+15)^2=24^2=576

kite=1/2 times diagonals=1/2 times AC times BD=1/2 times 24 times (BE+ED)=12 times (7+7)=12 times 14=168

so the shaded area=576-168=408 square inches

trapezoid=(base1+base2) times 1/2 times height

big one is base1=14, base2=25
height =10+12=22
area=(1/2)(14+24)(22)=(11)(38)=418

small one is base1=8
base2=25
height is 10
area=(1/2)(25+10)(10)=(5)(35)=175
so shaded area is 418-175=243 square cm
