A pet salon has fixed monthly expenses of $1,800 for rent, $400 for insurance, and a line of credit payment of $200 Initially, its variable expenses are given by V(q)=5.00q+100 , where q is the number of pets styled. Due to an increase in the cost of styling supplies, an additional $1.00 per pet is added to the variable expenses. What is the new equation for the total monthly expenses E(q) ?
Answer
A
cap e times q is equal to 5 point 0 0 q plus 2 comma 550
B
cap e times q is equal to 6 point 0 0 q plus 2 comma 300
C
cap e times q is equal to 6 point 0 0 q plus 2 comma 500
D
cap e times q is equal to 6 point 0 0 q plus 2 comma 550
Explanation
Add the fixed monthly expenses: $1,800 + $400 + $200 = $2,400. The extra $1.00 per pet raises the variable cost from $5.00q + $100 to $6.00q + $100. Thus, total expenses are E(q) = $6.00q + $100 + $2,400 = $6.00q + $2,500, which is choice D.
