Answer:
A)
- National brand cornflakes is 0.174 = .17/oz
- Store label cornflakes is 0.514 = .15/oz
B) The larger box is cheaper per ounce.
C) 2.09 – .30 = 1.79 for 12 ounces. So than $1.79/12= .15/oz.
They would both be the same so there would be no better deal.
Answer:
<em>b = 50√c</em>
Step-by-step explanation:
If b varies directly as the square root of c, this is expressed as;
b∝√c
b = k√c
k is the constant of proportionality
Given b = 100 and c = 4
100 = k√4
100 = 2k
k = 100/2
k = 50
Substitute k = 50 into the original expression:
Recall that: b = k√c
b = 50√c
<em>hence equation that can be used to find other combinations of b and c is b = 50√c</em>
