Answer:
a) 6 17/20
b) 10 31/60
Step-by-step explanation:
a) 9 2/20 - 2 1/4 = 137/20 = 6 17/20
b) 6 17/20 + 3 2/3 = 631/60 = 10 31/60
The solution of the given inequality is:
x ≤ 15.24

How to solve the inequality?</h3>
We know that the maximum that she can spend on gasoline is the 12% of $400.
That is:
(12%/100%)*$400 = 0.12*$400 = $48
Now, we know that each gallon of gas costs $3.15, then if x is the number of gallons of gas that she buys, we have the inequality:
x*$3.15 ≤ $48
To solve the inequality, we need to divide both sides by $3.15
x ≤ $48/$3.15
x ≤ 15.24
So the maximum number of gallons of gasoline that she can buy is 15 gallons (actually a little more).

First:
F=m.a
=4*7
=28N
Second:
F=m.a
28=m.2. (force is constant,so F=28N)
28/2=m
m=14kg.
I believe the answer is 104.
The price elasticity of demand of the pen will be -0.2.
<h3>How to compute the elasticity?</h3>
The demand and supply schedule will be:
Price Qd. Qs
$10. 250. 100
$20. 200. 90
$30. 180. 80
The price elasticity of demand from $1 to $2 will be:
= Percentage change in quantity demanded/percentage change in price
Percentage change in quantity demanded will be:
= (200 - 250)/250 × 100
= -20%
Percentage change in price will be:
= (20 - 10)/10 × 100
= 100%
Therefore, the elasticity of demand will be:
= -20/100
= - 0.2
The value gotten illustrates an inelastic demand.
In order to increase the total revenue, the price can be reduced as it will lead to more sales.
