Annika sells 6 inch pies for $5.00 and 8 inch pies for $9.00 each. last week she sold twice as many 6 inch pies as she did 8 inch pies. she made $133.00 from her sales. annika defined x as the number of 6 inch pies she sold and y as the number of 8 inch pies she sold. she wrote the system below. 6x+8y=133 2x=y which statements about the system are true? check all that apply. since the cost for each pie is $5 and $9, the first equation should be 5x+9y=133. since the 8 inch pies are 2 inches larger, the second equation should be x+2=y. since there are fewer 8 inch pies, the second equation should be x=2y to balance the values. the first equation is correct because 6x represents the money earned for 6 inch pies and 8y represents the money earned for 8 inch pies. the second equation is correct because there are more 6 inch pies and 2 times a number is always more.
