<span>In this question, the prices are Increased at a monthly rate of 2.3%. Since you are asked how much the percentage in a year and there is 12 month in a year, then you need to do the calculation 12 times.
The calculation would be (100%+2.3%)^12= </span><span>131.37344984%
That would be about 31.37% a year. </span>
The solution would be like
this for this specific problem:
Given:<span> x +y
= 390 </span>
2x + 4y = 1260
2x+4y=1260 ßdivide by 2
= x+2y=630
x+y=390 ßsubtract
= x+2y-x-y=630-390
y=240
x+240=390
x=390-240=150
<span>So, if they raised $1260 from the concession
stand, then they sold 240 sandwiches.</span>
So the coordinates of the center of the circle will be (-5,-7)
hope you know formula for equation of a circle
