Let the cost of one pound of candy be x and one pound of mint be y.
3x+2y=10.8 a
x+3y = 5.35 b
B*3 = 3x+9y = 16.05 b
b-a = 7y = 16.05-10.8= 5.25
y = 5.25/7 = 0.75
The cost per pound of mints is $0.75
Answer:
(D) (a + 4)/2
Step-by-step explanation:
To solve, you need to subtract the first equation from the second.
9p = 3a + 1
<u>- 7p = 2a - 3</u>
2p = 1a + 4
Now, you need to rearrange the equation so that is equal to p.
2p = a + 4
(2p)/2 = (a + 4)/2
p = (a + 4)/2
This gives you answer choice D.
