to determine her income level, we must add Mary's net salary during the first 3 months + total unemployment benefits for the first 13 weeks (April, May and June) + unemployment benefits for the next 13 weeks (July, August and September) + her normal income received during the last part of the year
total income = ($40,000 x 1/4) + ($947 x 13 weeks) + ($347 x 13 weeks) + ($40,000 x 1/4) = $10,000 + $12,311 + $4,511 + $10,000 = $36,822
total spending = normal spending level during 6 months + reduced spending level for the other 6 months
total spending = ($39,000 x 1/2) + ($39,000 x 1/2 x 9/10) = $19,500 + $17,550 = $37,050
