<PRE><B>Question 163832</B>
Tara sells packets of nasturtium seeds for $0.95 each and packets of Johnny-jumpup
 seeds for $1.43 each. She decides to offer a 16-packet spring-garden combination, 
combining packets of both types of seeds at $1.10 per packet.
 How many packets of each type of seed?
:
Let x = no. of 1.43 packs
then
(16-x) = no. of .95 packs
:
This equation should work:
:
1.43x + .95(16-x) = 1.10(16)
:
1.43x + 15.2 - .95x = 17.60
:
1.43x + .95x = 17.60 - 15.20
:
.48x = 2.40
x = {{{2.5/.48}}}
x = 5 pks of the 1.43 seed
and
16 - 5 = 11 pks of the .95 seed
:
;
Check solution in original equation:
1.43(5) + .95(11) = 1.10(16)
7.15 + 10.45 = 17.60; confirms our solution</PRE>
