Answer:
Washing Machine 1 $480 × .5030 = $241.44
$480 - $241 = $238.56
So Wahsing Machine #1 was $480 and was marked down by .5030% which takes off $241.44 which brings us to the total to $238.56
Washington Machine #2
$480 × .30% = $144 × .20% = $28.80
So Washing Machine 2 was $480 and was marked down by .30% which took off $144 and was marked down by an additional .20% which took off an additional $28.80 which brings the Grand Total of $307.20.
Joanne should buy the first Washing Machine rather than the second Washing Machine because the first Washing Machine is $68.64 cheaper than the second Washing Machine.
