ANSWER
$10
EXPLANATION
We are given that Walmart is selling 3 lemons for $1.20.
To find the cost of 25 lemons, we have to first find the cost of one lemon.
Since we have that:
3 lemons = $1.20
1 lemon = $x
Cross multiply:
3 * x = 1 * 1.20
=> x = 1.20 / 3
x = $0.40
So, one lemon costs $0.40
To find the cost of 25 lemons, we have to multiply $0.40 by 25.
That is:
25 * 0.40 = $10
25 lemons cost $10.
