Part A:
Price before tax: $49.99
Discount: 50% of $49.99 = 50% * $49.99 = 0.50 * $49.99 = $25.00
Discounted price: $49.99 - $25.00 = $24.99
Tax on discounted price: 8% of $24.99 = 8% * $24.99 = 0.08 * $24.99 = $2.00
Part B:
Total price: $24.99 + $2.00 = $26.99
Answer:
x+y=37-------(1)
5.5x+13.5y=355.5-----(2)
Put x=37-y in eqn 2
5.5(37-y)+13.5y=355.5
203.5-5.5y+13.5y=355.5
8y=152
y=19
x=18
Step-by-step explanation:
A regular pentagon is a polygon with five sides of equal length.
The perimeter of a regular polygon is the number of sides (n) multiplied by the length of one side (s).
P=ns
100=5s
s=20
The length of each side is 20 inches
Answer: £16.90
Step-by-step explanation:
From the question, we are informed that it costs £6.50 per hour to hire a tennis court at Meadway Tennis Club but that on Saturdays the cost is 30% more. The cost in Saturdays per hour will then be:
= £6.50 + (30% × £6.50)
= £6.50 + ( 0.3 × £6.50)
= £6.50 + £1.95
= £8.45
The cost to hire a court for 2 hours on a Saturday will then be:
= £8.45 × 2
= £16.90
