The total cost for tuition plus room and board at State University is $2,584.00. Tuition costs $100 more than twice room and boa
liq [111]

Answer:

$1756

Step-by-step explanation:

1.  More = Addition

2. Twice = Multiplication by 2

3. Tuition costs $100 more than twice room and board

   Tuition = 2x + 100

   $2584 = (2x + 100) + x

   $2584 = 3x + 100

4. Subtract 100 on both sides: $2484 = 3x

5. Divide both sides by 3: $828 = x

6. Plug it in to the tuition equation: Tuition = 2(828) + 100

                                                                       = $1756

Check Work: (828*2) + 100 = $1756

                      $1756 + 828  = $2584

How much do you save per class by taking the longer-term class: Weight Training, $200 for 18 weeks (54 classes) or $350 for 36 w
Vsevolod [243]

<u>Shorter term class:</u>

You pay $200 for 54 classes in total. So,

\frac{200}{54} =3.704 dollars per class (rounded to 3 decimal places)


<u>Longer term class:</u>

You pay $350 for 108 classes in total, So,

\frac{350}{108} =3.241 dollars per class (rounded to 3 decimal places)


Hence, by taking longer term classes, you save around 3.704-3.241=0.463 dollars.

Rounding to 2 decimal places, you save $0.46 per class.


ANSWER: You save $0.46 per class.
