Nashota picked 4 times as many apples as
Dulce. If Nashota picked 28 apples, how many
did Dulce pick?
Words
28 equals 4 times Dulce’s apples.
Variable
Let d represent Dulce’s apples.
Expression
28 = 4d
Write and Solve Equations
28 = 4d
Write the equation.
THINK 28 is equal to 4 times what number?
4 × 7 = 28
Replace d with 7.
Answer: So, d = 7. Dulce picked 7 apples.
Write and Solve Equations
To check your solution, replace the variable with 7.
Check
4d = 28
?
4 × 7 = 28
28 = 28
Write the equation.
Replace d with 7.
Simplify. The solution is correct.
