Answer: $47.66
Step-by-step explanation:
The cost of the sweater is calculated by multiplying .7 x $35. (70% represents the cost of the sweater since there is a 30% discount.). The sweater cost $24.50.
The cost of the jeans is .85 x $28 = $23.80.
The total cost is $24.50 + $23.80 = $43.80.
The tax rate is 8%, which is calculated by multiplying .08 x $43.80 = $3.86 in sales tax.
Including the sales tax, the total cost is $43.80 + 3.86 = $47.66

Answer:
78.04 square cm
Step-by-step explanation:
Area of shaded region = area of circle - Area of rectangle
Step-by-step explanation:
(a) the value of p that makes the lines parallel :
=> -4/-p = -5/7
5p = 7×(-4)
5p = -28
p = -28/5 = -5.6
(b) the value of p that makes the lines perpendicular :
=> -4/-p = -1 ÷ (-5/7)
4/p = 7/5
7p = 4×5
7p = 20
p = 20/7 = 2.86
