7 oz cost $2.38
15 oz cost $5.25
26 oz cost $8.58
Solution
<h3>7 oz</h3>
7 oz cost $2.38
1 oz cost x This is a proportion. 3 quatities are known. Find x Cross multiply.
7/1 = 2.38/x
7x = 2.38
x = $0.34 dollars
<h3>15 oz</h3>
15 oz cost 5.25
1 oz costs x
15.1/1 = 5,25 x Cross Multiply
15x = 5.25 * 1 Divide by 15
x = 5.25 / 15
x = $0.35
<h3>26 oz</h3>
26 oz cost 8.58
1 oz cost x
26/1 = 8.38/x Cross Multiply
26x = 8.38 Divide by 26
x = 8.38/20
x = 0.32 dollars
Answer
7 oz cost 0.34
15 oz cost 0.35
26 oz cost 0.32
<h3>The best buy is 0.32 / oz for 26 oz</h3>
A^2 + b^2 = c^2 in right triangles.
4^2 + b^2 = 8.5^2
16 + b^2 = 72.25
b^2 = 56.25
b = 7.5
