Answer:
- 14 apples
Step-by-step explanation:
Let
- Number of apples = a
- Number of students = s
According to question we have equations
- a = 3s + 2
- a = 4s - 2
Find the number of students by substitution
- 3s + 2 = 4s - 2
- 4s - 3s = 2 + 2
- s = 4
Find the number of apples
- a = 3*4 + 2 = 12 + 2 = 14
Answer:
14 apples
Step-by-step explanation:
Let x = number of students
Let y = total number of apples
Create a system of equations with the given information.
Equation 1
If she gave each student 3 apples, she would have 2 apples left:
⇒ y - 3x = 2
Equation 2
If she gave each students 4 apples each she would be 2 short:
⇒ y - 4x = -2
Rewrite Equation 1 to make y the subject:
⇒ y = 2 + 3x
Substitute this into Equation 2 and solve for x:
⇒ (2 + 3x) - 4x = -2
⇒ 2 + 3x - 4x = -2
⇒ 2 - x = -2
⇒ -x = -4
⇒ x = 4
Substitute the found value of x into the rewritten Equation 1 and solve for y:
⇒ y = 2 + 3(4)
⇒ y = 2 + 12
⇒ y = 14
Therefore, Mrs Reyes had 14 apples.
