Answer:

<em>an= 3+12n </em>

Step-by-step explanation: <em>the sequence is 15,27,39,51 The first term is : a 1= 15 The common difference of this sequence : d= 27 - 15 </em>

<em>The nth term of an arithmetic sequence is given by formula an= a + (n - 1 ) d . so a n for the sequence will be : </em>

<em>an =15+ (n-1) 12 </em>

<em>an = (15)+12n - 12</em>

<em>an = 3 + 12n</em>

Hamburger is on sale for 20% off the normal $3.70 price. How much can you save per pound by buying the meat on sale? Explain you
Nitella [24]

Answer:

$0.75

Step-by-step explanation:

Given

Normal price - $3.70

If Hamburger is on  sale for 20% off the normal price

The amount that can be saved will  be 20% of $3.70

Amount that can be saved = 20/100 * 3.70

Amount that can be saved  = 1/5 * 3.70

Amount that can be saved  = 3.7/5

Amount that can be saved  = 0.75

Hence the Amount that can be saved on $3.70 is $0.75
