Answer:
Wage = 7x,x ∈ [0,1,2,3,4]
Statements such as these can be converted into a mathematical language which is known as equations that can help us solve for the unknown. In this question, we need to find the wages for Charles who babysits. We have been given some statements which need to be translated into mathematical equations.
A typical equation has two sides, a right-hand side, and a left-hand side.
Let the total wage be given by Wage and the total number of hours worked to be given by x Thus, we can denote the function in functional notation as
Wage = 7x,x ∈ [0,1,2,3,4]
Wage = 7(4),4 ∈ [0,1,2,3,4] The symbol ∈ indicates set membership and means “is an element of”
Wage = 7(4),4 is an element/set of [0,1,2,3,4]
