Answer:
$1,330
Step-by-step explanation:
Sarah makes a minimum monthly payment of $20
If she is required to make this payment for a period of six months, then the total payment is
= $20×6
= $120
Since Sarah purchased the swing set for $1,450, then the balance at the beginning of the seventh month can be calculated as follows
= $1,450-$120
= $1,330
Hence the balance at the beginning of the seventh month is $1,330
