Since Jane wants to buys some lollipops, Jane has $13 dollars.
To answer the question, we need to solve simultaneous equations
<h3>What are simultaneous equations?</h3>
Simultaneous equations are pairs of equations that contain two unknowns
<h3>How to calculate how much Jane has using simultaneous equations</h3>
Let
- x = price per lollipop and
- y = total amount Jane has
We know that If she buys 2 lollipops, she will have 3 dollars left, so we have that
y - 2x = 3 (1)
Also, If she wants to buy 3 lollipops, she will need 2 more dollars. So, we have that
y + 2 = 3x (2)
<h3>The required simultaneous equations</h3>
So, the required simultaneous equations are
y - 2x = 3 (1)
y + 2 = 3x (2)
From (1), x = (y - 3)/2
Substituting x into (2), we have
y + 2 = 3x (2)
y + 2 = 3(y - 3)/2
2(y + 2) = 3(y - 3)
2y + 4 = 3y - 9
2y - 3y = -9 - 4
-y = -13
y = -13/-1
y = 13
So, Jane has $13 dollars.
