Answer:
(a) The constant of proportionality is 0.25
(b) 1 apple = $0.25
(c) $3 = 12 apples
Step-by-step explanation:
Given

Solving (a): The constant of proportionality;
For an equation:

Where
k = constant of proportionality
By comparing:
to 

Hence, the constant of proportionality is 0.25
Solving (b): What information does
gives.
It represents the unit rate.
<em>So, it means that 1 apple costs $0.25</em>
<em></em>
Solving (c): Number of apples for $3.
This means that 
Substitute 3 for c in 

Make n the subject


The equation would be
8 = 6x + 2
the “number” is unknown, so it’s x.
6 times the number would be 6x.
The sum of 6x and 2 means adding together 6x and 2, so 6x + 2
And it’s supposed to equal 8
Answer:
Step-by-step explanation:
Amount at hand = $62
Amount owed = $13 + $39
= $52
$62 - $52
= $10
Answer: 5 feet of wood for 2.23
because the unit rate for each foot of wood is .45 compared to getting 6 feet for 2.95. 2.23 plus .43 (the cost for one foot) would be 2.63 making the wood much cheaper than the 6 foot option.
