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

Let

x> the number of 6-inch pies Annika sold 

y> the number of 8-inch pies Annika sold 

we know that

x=2y> equation 1

5x+9y=133---> equation 2

substitute the equation 1 in equation 2

5*[2y]+9y=133

10y+9y=133

19y=133

y=7

x=2y> x=2*7> x =14

Only option 1 is correct
