Ethan has $20 saved and he earns $6.50 per hour. he wants to have at least $100 in his savings account.

write an inequality to represent how many hours ethan will need to work to save at least $100.

Alrighty lets work this out. Ethan has 20 dollars already so if we do the math we can subtract 100-20=80 so we know that Ethan needs to earn 80 more dollars to have 100 dollars in his savings account. We also know that Ethan earns $6.50 per hour so we can divide 80 from 6.50 which is 12.30, So he works 12 hours and 30 minutes more to earn one hundred dollars. I hope this helped!

Step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
