(A) 64%
(B) 68%
(C) 72%
(D) 76%
(E) 80%
Since we're asked to find a PERCENT (and not an actual value), we can
assign a nice value to the Lee family's total income.
In May Mrs Lee's earnings were 60 percent of the Lee family's total income
Let's say
$100 = Lee family's total income IN MAY
This means $60 = Mrs Lee's earnings IN MAY
In June Mrs Lee earned 20 percent more than in May.
Mrs Lee's earnings in June = $60 + (20% of $60)
= $60 + $12
=
$72
If the rest of the family's income was the same both months, then, in June, Mrs Lee's earnings were approximately what percent of the Lee family's total income ?
Since Mrs. Lee made an extra $12 in June, the family's TOTAL income for June =
$100 + $12 =
$112
Percent = (100)
$72/
$112
≈64%
Answer: A
