Vanessa earns a base salary of \( \$ 400.00 \) every week with an additional \( 5 \% \) commission on everything she sells. Vanessa sold \( \$ 1650.00 \) worth of items last week. What was Vanessa's total pay last week? \( \$ \)

posited \( \$ 3400 \) into a savings account \( 0.2 \% \). Find the amount in the savings

in deposited \( \$ 2700 \) into a savin te of \( 0,3 \% \). Find the amount in

If \( x \) represents the number of items produced, (a) write a cost function, (b) find a revenue function if each item sells for the price given, (c) state the profit function, (d) determine analytically how many items must be produced before a profit is realized (assume whole numbers of items), and (e) support the results of part (d) graphically. The fixed cost is \( \$ 500 \), the cost to produce an item is \( \$ 20 \), and the selling price of the item is \( \$ 45 \). (a) The cost function is \( \mathrm{C}(\mathrm{x})=\square \). (Simplify your answer. Do not factor.) (b) The revenue function is \( \mathrm{R}(\mathrm{x})=\square \). (Simplify your answer. Do not factor.) (c) The profit function is \( \mathrm{P}(\mathrm{x})=\square \). (Simplify your answer. Do not factor.) (d) At least \( \square \) items must be produced before a profit is shown. (Type a whole number.) (e) Choose the correct graph to the right.
