Oliver saves 10% of his weekly earnings for living expenses. He usually makes $520 each week.
A- Calculate the amount of money Oliver saves in one week.
B- There are 52 weeks in one year. If Oliver saves the same amount each week for 6 months, how much will he save?

See explanation

Step-by-step explanation:

A. Calculate the amount of money Oliver saves in one week.

This will be:

= 10% × $520

= 1/10 × $520

= 0.1 × $520

= $52

B. There are 52 weeks in one year. If Oliver saves the same amount each week for 6 months, how much will he save?

This will be:

= $52 × 52weeks/2

= $52 × 26

= $1352

Note that 6 months will be:

= 52 weeks/2

= 26 weeks.

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

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
