Jactina buys 4 pounds of Turkey and 2 pounds of ham. she pays a total of $30.00. if Ham costs $6.00 per pound , how much does the Turkey cost per pound ?

Let t = cost per pound of turkey
Let h = cost per pound of ham

4t + 2h = 30
t = h - 1.5

substitute h-1.5 in place of t in 1st equation

4(h-1.5) + 2h = 30
4h - 6 + 2h = 30
6h - 6 = 30
6h = 36
h = 6

t = h-1.5 = 4.5

1 pound of turkey costs $4.50
1 pound of ham costs $6.00

cost of 1 pound each $10.50

The answer is 1 because you have to flip the sign when dividing by negative number and 3
