Question

Mandy has four dollars less than Mindy. Mindy has eight dollars. How many dollars does Mandy have? Set up an equation that uses an unknown, x, for the number of dollars that Mandy has. Solve the equation for x.

Answer 1

Step 1:

Mindy = $8

Mandy has $4 less than Mindy

Hence,

Mandy has = $8 - $4 = $4

Mandy has = $4

Step 2:

Mindy = $8

Mandy = $x

Mandy has $4 less than Mindy

Therefore

x + 4 = 8

x = 8 - 4

x = $4
