Answer: 75% off
Step-by-step explanation:
Your first sweater is the full 100% of the cost. The second it only 50 percent. If you add these to find out how many percent you will pay which is 150 for both. If you were to divide by 2 you get 75 percent off each sweater. The first sweater is $48 the second you multiply by .5 (as its 50 percent off ) and the cost is $24 dollars. 48 plus 24 is 72 then that divided by 2 is 36. Now 36$ is the price per sweater. 36/48 or 3/4 (which is 75%)
Lets write an equation for each guy's shots and score:
4A + 2B = 18
3A + 3B = 21
To solve we multiply the first equation by -3 and the second by 2:
-12A - 6B = -54
6A + 6B = 42
--------------------
-12A + 0 = -12
A = 1
to find B we substitute in the first equation:
<span>4A + 2B = 18
</span><span>4(1) + 2B = 18
</span><span>4 + 2B = 18
</span>2B = 14
B = 7
therefore there were given 7 points in an arrow in B
