Lauren wants to buy 3 shirts at 15.00 each. at home, she calculates the total cost as 46.20 using the sales tax of 8% . at the store, the cashier tells lauren the total cost is 48.60 . who is wrong and what mistake did he or she make ?

Answer

Lauren is wrong. Maybe she added incorrectly??

Step-by-step explanation:

3 * 15 = 45

45 * 8% = 3.60

45.00 + 3.60 = 48.60

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

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
