Solving a system of equations, we see that she can plant 20 tomatoes and 20 squashes.
<h3>How many tomatoes and how many squash can Kayla plant?</h3>
Let's define the variables:
- t = number of tomatoes.
- s = number of squaches.
The space is enough for 40 plants, then:
t + s = 40
And we know that she has a total of $80 to spend (we assume that she spends it all)
t*$1 + s*$3 = $80
Then our system of equations:
t + s = 40
t*$1 + s*$3 = $80
To solve this, we can isolate one of the variables in the first equation, for e xample if we isolate t, we get:
t = 40 - s
Now we can replace that in the other equation:
(40 - s)*$1 + s*$3 = $80
Now we can solve that for s:
$40 - s*$1 + s*$3 = $80
s*$2 = $40
s = $40/$2 = 20
Then she will buy 20 units of squash, and the other 20 plants will be tomatoes.
