Answer:
8 roses
Step-by-step explanation:
First start by subtracting $18.69 by $5.25 because you already know how much the carnations cost and how much the bouquet cost in all. When you subtract 18.69 by 5.25 you should get $13.44. If each rose cost $1.68 then divide 13.44 by 1.68 to get the amount of roses in the bouquet.
It is the first equation, 3x-y=-7.
It is the only equation that both sets of points satisfy as true.
Volume of prism = 1/2 a c h
= 1/2 × 7 × 9 × 15 = 472.5
Therefore, the vorrect answer is A. 472.5 ft
