Let
x-------> ounces of <span>ground sumac
y-------> ounces of </span><span>ground thyme
we know that
x+y=25------> x=25-y------> equation 1
1.25x+1.5y=1.35*25-----> 1.25x+1.5y=33.75-----> equation 2
substitute equation 1 in equation 2
1.25*[25-y]+1.5y=33.75------> 31.25-1.25y+1.5y=33.75
0.25y=2.5
y=10
x=25-y-----> x=25-10-----> x=15
the answer is
15 </span>ounces of ground sumac
10 ounces of ground thyme
Answer:
