Answer:
A pound of a JELLY BEANS cost $2.5
A pound of TRAIL MIX cost $1.5
Step-by-step explanation:
From the question, we can draw out two equations and solve them simultaneously.
We should make some mild assumptions to make it easier:
Let Jelly beans be j
Let Trail mix be t
Therefore, we can extract these equations.
5j + 3t =$ 17 ...........i
2j + 12t = $ 23...…..ii
Let's Multiply equation (I) by 4 so that we can easily eliminate.
20j + 12t = $ 68..... iii
Let equation (iii) minus equation (ii)
18j + 0t = $45
18j = $45
j = $45/18
j = $2.5
A pound of a JELLY BEANS cost $2.5
Let's substitute j= $2.5 in EQUATION (I) so as to solve for TRAIL MIX.
5j + 3t =$ 17
5(2.5) + 3t = 17
12.5 + 3t = 17
3t = 17 - 12.5
3t = 4.5
t = $1.5
A pound of TRAIL MIX cost $1.5
Think of sqrt(2) as a variable.
3x - x = 2x
If x = sqrt(2), then answer is 2sqrt(2)
