Answer 1

53(1 + x)

the 53 is the cost of the meal without the tax

the x is gonna be the percentage of the tip u want to leave...in decimal form

so lets say u are going to leave a 5% tip.....5% = 0.05
ur equation would be 53(1 + 0.05) = 53(1.05) = 55.65...cost of meal and tip

Answer 2

⇒The expression which represents the total cost of a meal including the tip

=53×(1+x)

Using Distributive property of Multiplication with respect to Addition

=53+53 x

`=53 +53 * (100x)/(100)`

--------------------------------------(1)

If p% is the amount of tip given ,and if A is the Actual Bill , then it can be written as

= A +A×p%-------------(2)

Equating (1) and (2)

`A+A* (p)/(100)=53+53 * (100x)/(100)\\\\A=53\\\\ (p)/(100)= (100x)/(100)\\\\p=100x`

Total Cost of Meal =$53

Amount used for tip=$ 100x
