Answer: $1.50
Step-by-step explanation:
Cost price of watermelon = $1.25
Profit percent = 20%
Profit = Profit percent × Cost price
= 20% × $1.25
= 20/100 × $1.25
= 0.2 × $1.25
= $0.25
Selling price = Cost price + Profit
Selling price = $1.25 + $0.25
Selling price = $1.50
They should charge $1.50 for the watermelons
Your answer is at the top good luck!

Step-by-step explanation:
hello
we are going to solve this question via substitution method
![\begin{gathered} 3x-4y=-5\ldots\text{equ}1 \\ x=y+2\ldots\text{equ}2 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%203x-4y%3D-5%5Cldots%5Ctext%7Bequ%7D1%20%5C%5C%20x%3Dy%2B2%5Cldots%5Ctext%7Bequ%7D2%20%5Cend%7Bgathered%7D)
put equation 2 into equation 1
![\begin{gathered} 3x-4y=-5 \\ x=y+2 \\ 3(y+2)-4y=-5 \\ 3y+6-4y=-5 \\ -y+6=-5 \\ -y=-6-5 \\ -y=-11 \\ \text{divide both sides by -1} \\ -\frac{y}{-1}=-\frac{11}{-1} \\ y=11 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%203x-4y%3D-5%20%5C%5C%20x%3Dy%2B2%20%5C%5C%203%28y%2B2%29-4y%3D-5%20%5C%5C%203y%2B6-4y%3D-5%20%5C%5C%20-y%2B6%3D-5%20%5C%5C%20-y%3D-6-5%20%5C%5C%20-y%3D-11%20%5C%5C%20%5Ctext%7Bdivide%20both%20sides%20by%20-1%7D%20%5C%5C%20-%5Cfrac%7By%7D%7B-1%7D%3D-%5Cfrac%7B11%7D%7B-1%7D%20%5C%5C%20y%3D11%20%5Cend%7Bgathered%7D)
put y = 11 into equation 1 or 2
with equation 1
put y = 11
![\begin{gathered} 3x-4y=-5 \\ y=11 \\ 3x-4(11)=-5 \\ 3x-44=-5 \\ 3x=-5+44 \\ 3x=39 \\ \text{divide both sides by 3} \\ \frac{3x}{3}=\frac{39}{3} \\ x=13 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%203x-4y%3D-5%20%5C%5C%20y%3D11%20%5C%5C%203x-4%2811%29%3D-5%20%5C%5C%203x-44%3D-5%20%5C%5C%203x%3D-5%2B44%20%5C%5C%203x%3D39%20%5C%5C%20%5Ctext%7Bdivide%20both%20sides%20by%203%7D%20%5C%5C%20%5Cfrac%7B3x%7D%7B3%7D%3D%5Cfrac%7B39%7D%7B3%7D%20%5C%5C%20x%3D13%20%5Cend%7Bgathered%7D)
fro the calculations above, the solutions to the equations with the value of x and y are (13) and (11)
