Samantha solved an equation, as shown below:

Step 1: 15r = 105
Step 2: r = 105 - 15
Step 3: r =90

Part A: Is Samantha's answer correct or incorrect? If it is incorrect, explain why it is incorrect and show the correct steps to solve the equation. (6 points)

Part B: How many solutions does this equation have? (4 points)

Step-by-step explanation:

A) Samantha's answer is incorrect because 15r ----> 15*r. So when 15 goes to other side, multiplication will change to division (not subtraction)

15r = 105

divide both sides by 15

B)This equation has only one solution.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
