Answer 2

The expressions that represent the retail price of the cars are c + 0.19 c and 1.19c

Explanation:

Retail Price = Cost Plus Mark-Up

Retail Price = Cost + Mark-Up

Cost = c

Mark-Up is a percentage of cost price

Mark-Up = 19% of Cost Price

FIRST EXPRESSION

Retail Price = Cost + 19% of Cost Price

Retail Price = Cost + 19% x Cost Price

Substitute c for cost

Retail Price = c + 19% x c

Retail Price = c + (19/100 x c)

Retail Price = c + 0.19 x c

Retail Price = c + 0.19 c

Therefore the first expression that represents the retail price of the cars is c + 0.19 c

SECOND EXPRESSION

Retail Price = c + 0.19 c

Simplify the expression by performing addition operation on the algebraic expression.

Retail Price = 1.19 c

Therefore the second expression that represents the retail price of the cars is 1.19 c
