35 students × 18 classes = 630 total students
630 total students ÷ 30 (new class size) = 21

therefore, it requires 21 new classes to reduce the class size to 30.

Area of the front and back faces = 2 [  (8.1 x 8.1) + (1/2 x 8.1 x 2.1  ] = 148.23 in²

Area of the right and left faces = 2 [ 11.8 x 8.1 ] = 191.16 in²

Area of the top = 2 [4.6 x 11.8] = 108.56 in²

Total Area =  148.23 in² +  191.16 in² + 108.56 in² = 447.95 in²

Answer: Theo will need to paint about 447.95 in².

1.) The answer is 825.75 (multiply the given tax rates to the gross pay)
    2,785 x 13% federal taxes = 362.05
    2,785 x 9% state tax         = 250.65
    2,785 x 7.65% FICA          = <u>213.05
</u>                                                 825.75
<u>
</u>2.) The answer is 288.60 (multiply the interest rate to the balance, no need to add a late payment fee since they paid on 6/1, not after)
    2,748.56 x 10.5% = 288.60

3.) The answer is 182.13  (multiply the APR to the original purchase price, no need to add the sales tax)
<u />    1,500 x 11.75% = 182.13

4.) The answer is 371.92 (deduct the reward to the interest)
    Interest : 2,975.34 x 13.5% = 401.67
    Reward : 2,975.34 x 1%      = <u>  29.75</u>  
                                                    371.92

5.) The answer is  1,339.13 (deduct the interest to the monthly payment)
    Monthly payment : 2,236.00
    Monthly interest :   <u>   896.87</u> [(231,450 x 4.65%) / 12 months]
<u />                                    1,339.13

Hope this helps! :)
