Answer:
Amount of bill after discount = $55.25
Amount of tip left = $13
Total money spent at the restaurant = $68.25
Step-by-step explanation:
Original bill amount of Mr. Hudson = $65
Discount card value = 15% of the bill
Tip offered = 20% of the original amount
To find:
Amount of bill after the discount of 15%.
Amount of tip left.
Total amount spent in the restaurant.
Solution:
Let us apply the percentage here to find the values of total discount, total tip offered.
Discount = 15% of $65
Amount of bill after discount = $65 - $9.75 = $55.25
Amount of tip left = 20% of $65
Total money spent at the restaurant = Amount of bill after discount + tip offered = $55.25 + $13 = <em>$68.25</em>

The answers are:
Amount of bill after discount = $55.25
Amount of tip left = $13
Total money spent at the restaurant = $68.25
a) 2 (5x-3) = 24
= 10x -6 = 24
= 10x = 24+6
= 10x = 30
= x= 30/10
b) 5 (2x+1) = 50
= 10x+5=50
= 10x = 50-5
= 10x = 45
= x = 45/10
c) (3x+4)/2=9.5
= (3x+4)/2=95/10
( On cross multiplication )
= 10(3x+4) = 2×95
= 30x+40=190
= 30x=190-40
= 30x=150
= x=150/30
(on simplification)
d) (7+2x)/3=5
(On cross multiplication)
= 1(7+2x)=5(3)
= 7+2x=15
= 2x=15-7
= 2x=8
= x=8/2
(on dividing)
