The manager of a garden store ordered two different kinds of marigold seeds for her display. The first type cost her $1 per packet and the second type cost $1.26 per packet. How many packets of the first type did she purchase if she bought 50 more of the $1.26 packets than the $1 packets and spent a total of $402?
a. 150
b. 200
c. 250
d. 100
x = 1 dollar pax
x+50 = 1.26 pax
(1) x + 1.26(x+50) = 402
x + 1.26x =339
x = 150 of the 1 dollar pax
