Step-by-step explanation:
<u>Given:</u>
2/20 : 1/40
A). First re-write the ratio as follows;
(i) Change the ratio sign to division (÷). i.e
2/20 ÷ 1/40
(ii) Solve the expression by changing the division to multiplication(×). This also means you will need to swap the numerator and the denominator of the second term. i.e (1 / 40) becomes (40 / 1)
(2/20) × (40 / 1) = × =
B). Now convert the result from above to unit rate. A unit rate is a rate in which the denominator has a value of 1.
So to convert to unit rate, we keep simplifying until the denominator becomes 1.
And since the denominator is already 1, there is no need for further simplification.
Therefore, 2/20 : 1/40 to unit rate is

Answer:
First blank: non-viable solution because the costs aren't less than the revenue
Second blank: viable solution because the costs are less than the revenue
Step-by-step explanation:
First: Insert the x into the equation and work it out to see if it is less than the y.
(30,90) x=30 y=90
y=1.5(30)+45
y=45+45
y=90
Non-Viable
Second: Insert the x into the equation and work it out to see if it is less than the y.
(60,160) x=60 y=160
y=1.5(60)+45
y=90+45
y=135
Viable
