To raise additional money for the school, the pep club decided to open the concession stand during the tournament and sell sandwiches and bottled water. Club members sold the water for $2 a bottle and the sandwiches for $4 each. They sold a total of 390 items. If they raised $1260 from the concession stand, how many sandwiches did they sell? They sold
sandwiches.

is there answer choices?

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

no
