A couple bought a new television which had an original price of $4480. Thanks to a markdown of all merchandise in the electronics departmental store, they enjoyed a discount of 32% of the original price of the television. How much did they have to pay each month if they had signed up for a monthly installment plan which spanned over 7 months?
The markdown they enjoyed was 32/100*$4480=$<<32/100*4480=1433.60>>1433.60
Since the couple bought the television at a markdown, they only had to pay $4480-$1433.6=$<<4480-1433.6=3046.4>>3046.4
When they used the monthly installment plan, each installment they had to pay was $3046.4/7=$<<3046.4/7=436.63>>436.63. Answer: \boxed{437}.
