Answer:
Frank is 56 years old
Millie is 44 years old
Step-by-step explanation:
Since three times Millie's age is 132, you can figure out her age by dividing 132 by 3. Since Frank's age is 12 years older than Millie's, add 12 to 132 divided by 3.
Millie's age equation:
x = 132/3
x = 44 years old
Frank's age equation:
x = (132/3) + 12
x = (44) + 12
x = 56 years old
Use this equation:
d=5x+225
To make $400, use this
400=5x+225
To solve, subtract 225 from each side.
Leaving you with 175=5x
Then decide by 5
