Adress shop sold 150 dresses on sunday with sales receipts of $1. the plain dresses were sold for fifty dollar each while the dyed dresses were sold for seventy dollar each. how many of each type of dresses were sold?

plain dresses = 25

dyed dresses =125

Step-by-step explanation:

number of plain dresses - x

number of dyed dresses - y

X + Y = 150 (1)

50X + 70Y = 10000 (2)

(2)/50

X + 7/5 Y = 200 (3)

(3) - (1)

0 + 7/5Y - Y = 50

2Y = 250

Y = 125

; X = 25

Plain dresses =25, and dyed dresses= 125

Step-by-step explanation:

Let P rep the plain dresses, and D, the dyed ones,

P+D=150 (i)

50P+ 70D= 10000(ii)

Using equation i

P=150-D

Replace P in Equation ii

50(150-D)+ 70D =10000

7500-50P+70D=10000

20D= 2500

D= 125

Therefore; P=150-125= 25

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
