Question

Bernice monthly paycheck can be represented by p(d) = 21od + 1100. She also earns money babysitting which can be represented by b(d) = 36d + 100. In both functions, d represents the number of weekdays. Write a function, t(d) , that represents Bernice's total monthly income.

Answer 1

t(d) = 246d + 1200

Explanation:

t(d) = p(d) + b(d)

Where,

t(d) = Bernice's total monthly income

p(d) = monthly paycheck

b(d) = babysitting earnings

d = number of weekdays

p(d) = 210d + 1100

b(d) = 36d + 100

t(d) = p(d) + b(d)

= (210d + 1100) + (36d + 100)

= 210d + 1100 + 36d + 100

= 246d + 1200

t(d) = 246d + 1200
