Answer:
<em>D </em><em>$0.60</em>
Step-by-step explanation:
Since <em>a dozen is equal to 12</em>, we will first <em>multiply $2.75 by 12</em>, and we get <em>$33</em>. Now <em>subtract $33 by $25.80</em> dollars, which is <em>$7.2.</em> Now we know that we saved <em>$7.2 </em>out of a dozen cupcake's, but we have to find <em>how much we saved on </em><u><em>each</em></u><em> cupcake</em>. So lets <em>divide $7.2 by 12</em> and we get <em>$0.60. </em> Therefore, you saved <em>$0.60</em> on each cupcake.

Answer:
y = 5x+3
Step-by-step explanation:
a general line is represented by the equation:
y = mx + n
a line with m=5, that goes through (-1,-2), should satisfy the equation:
-2 = 5×(-1) + n
this is because any point on the line, satisfies it's equation.
from this we get n = 3, hence our answer
