Question 3 ( 1 point) Determine the number of months required for \( \$ 750 \) to earn \( \$ 31.25 \) simple interest at \( 3.5 \% \) per-annum. a) 15 months b) 12 months 14 months d) 11 months e) 10 months

The cost of operating the Maintenance Department is to be allocated to four production departments based on the floor space each occupies. Department A occupies \( 900 \mathrm{~m}^{2} \); Department B, \( 800 \mathrm{~m}^{2} \), Department C, \( 1200 \mathrm{~m}^{2} \); and Department D, \( 500 \mathrm{~m}^{2} \). If the July cost was \( \$ 57,800 \), how much of the cost of operating the Maintenance Department should be allocated to each production department? The operating cost for Department A is \( \$ \square \). (Simplify your answer.)

Simplify the following. \( \frac{\$ 4284}{1+0.28 \times \frac{292}{365}} \) \( \frac{\$ 4284}{1+0.28 \times \frac{292}{365}}=\$ \square \) (Type an integer or a decimal.)

2. Peter gets a salary of \( \$ 125 \) per week. He wants to buy a new television that costs \( \$ 3,960 \). If he saves \( \$ 55 \) per week, which of the following expressions could he use to figure out how many weeks It will take him to save up enough money to buy the new TV? (d) \( \$ 3,960 \div(\$ 125-\$ 55) \) () \( \$ 3,960-(\$ 125)(\$ 55) \) () \( (\$ 3,960 \div \$ 125) \div \$ 55 \) (D) \( \$ 3,960 \div \$ 55 \)

Solve for the indicated variable and select the correct answer. \( \begin{array}{l}1+r t=\frac{A}{P} \text { for } P \\ P=\frac{A}{1+r t} \\ P=\frac{1+r t}{A} \\ P=1+r t-A \\ P=A(1+r t)\end{array} \)

The cost of operating the Maintenance Department is to be allocated to four production departments based on the floor space each occupies. Department A occupies \( 900 \mathrm{~m}^{2} \); Department \( \mathrm{B}, 800 \mathrm{~m}^{2} \); Department \( \mathrm{C}, 1200 \mathrm{~m}^{2} \); and Department \( \mathrm{D}, 500 \mathrm{~m}^{2} \). If the July cost was \( \$ 57,800 \), how much of the cost of operating the Maintenance Department should be allocated to each production department? The operating cost for Department A is \( \$ 15,300 \). (Simplify your answer.) The operating cost for Department B is \( \$ 13,600 \). (Simplify your answer.) The operating cost for Department C is \( \$ \$ \) (Simplify your answer.)
