Answer:
Δ MNO ≅ ΔXYZ by AAS postulate.
Step-by-step explanation:
Given:
,
, and YO = NZ.
Consider YO = NZ
Add OZ on both sides
YO + OZ = NZ + OZ
YZ = NO
Consider triangles Δ MNO and ΔXYZ.
Statement Reason
1. Given
2. Given
3. YZ = NO ∵ YO = NZ
Therefore, the two triangles Δ MNO and ΔXYZ are congruent to each other from AAS postulate as two corresponding angles and a corresponding side are equal to each other.
For this case what we should do is find the cost per ounce.
For this, we can use the following rule of three:
5 ounces ----------------------> 2.50 $
1 oz ------------------------> x
From here, we clear the value of x.
We have then:
Answer:
The unit cost per ounce is given by:
x = 0.5 $ / ounce
