Afamily of four had dinner together at a restaurant. write two expressions for calculating their total bill if they leave a 15% tip. let c represent the cost of their meal before tipping.

Expression of total bill is t = 1.15c where t represents total bill and c represents cost of the meal before tipping.

Solution:

Given that family of four had dinner together at restaurant.

Percentage of tip left by family = 15%

Cost of the meal before tipping is represented by variable c.

Need to determine expression for total bill paid.

Let’s assume total bill be represented by variable t.

total bill = cost of the meal before tipping + 15% of tip

15% of tip means 15% of cost of meal before tipping.

=> Total bill = cost of the meal before tipping + 15% of cost of meal before tipping.

 On substituting given variable c and assumed variable t in above expression, we get

t = c + 15% of c

Hence required expression of total bill is t = 1.15c where t represents total bill and c represents cost of the meal before tipping.

i think it is c, not positive though
