8.28÷18 = 0.46

0.46 is the cost if 1 stamp

cost of 12 stamps= 0.46×12 = $5.52

happy to help :)

Answer: $5.52

Step-by-step explanation:

Given: Sam paid $8.28 for 18 stamps.

Thus, the cost of 18 stamps = $8.28

Then the cost of 1 stamp=

Thus, the cost of 1 stamp=$0.46

With the same rate , the cost of 12 stamps=

Therefore, the cost of 12 stamps= $5.52

hence, it costs $5.52 to Sam to buy 12 stamps.

A box contains seven action, six comedies, eight dramas, and five science fiction films. Find the probability of choosing a come

Montano1993 [528]

7 action, 6 comedies, 8 dramas and 5 science fiction. So our sample space or possible outcomes is 7+6+8+5, or 26.

one thing to note is that AND means multiplication.

P(comedy) will be 6/26, favorable outimes over possible outcomes, and then we put it back, because we're putting it back in the box, the sample space is again 26, therefore P(drama) is 8/26, and then we multiply both.

$\bf \stackrel{P(comedy)}{\cfrac{6}{26}}~~\stackrel{\stackrel{AND}{\downarrow }}{\cdot }~~\stackrel{P(drama)}{\cfrac{8}{26}}\implies \cfrac{3}{13}\cdot \cfrac{4}{13}\implies \cfrac{12}{169}~~\approx~~0.071\\\\\\0.071\cdot 100\implies \stackrel{\%}{7.1}$
