Adv Review #11

A toy company spends $1500 per day for factory expenses plus $8 to make each teddy bear.  They sell the teddy bears for $12 a piece.  Which equation could be used to find the number of bears t the company has to sell in one day to equal its daily cost?

• 1500 + 8t = 12
• 12 + 8t = 1500
• 1500 + 8t = 12t
• 8t = 12t + 1500

472 students are going on a field trip.  120 students will be returning home and the rest will be spending the night in cabins. If a cabin sleeps 8 people, how many cabins need to be rented?

• 4 cabins
• 44 cabins
• 59 cabins
• 74 cabins

Solve.
(2x - 3) / 4  = 9

• x = 24
• x = 12
• x = 17.5
• x = 19.5

−2|−2r − 4| = -12

• {-5,1}

• {-5,-1}

• {-5}

• No Solution

Solve for p
$SA\ =hp\ +\ 2B$

• $\frac{SA-2B}{h}=p$

• $\frac{SA}{h}-2B=p$

• $\frac{SA-h}{2B}=p$

• $SA-2B-h=p$
