Annabelle collected a weekly allowance of $30. She spent a third of it buying junk food, then spent another $8 on sweets. Out of guilt she decides to save the rest. How much did she save?
How much did Annabelle spend on junk food? ** A third of $30 is $30*(1/3) = $<<30*(1/3)=10>>10
How much did Annabelle spend on junk food? ** She spent $10 from $30 leaving $30-$10 = $20
How much did Annabelle spend on sweets? ** She spent another $8 leaving $20-$8 = $<<20-8=12>>12 which she saved
