A vendor at a craft show sold items for $4.50, $6.00, and $7.50.
Altogether, the vendor sold 87 items for a total of $489. The vendor
sold five more items for $6.00 than for $7.50.
Let x = number of $4.50 craft items sold
Let y = number of $6.00 craft items sold
Let z = number of $7.50 craft items sold
Which system of equations could you use to determine how many
of each item were sold?
x + y + z = 489
z = y + 5
4.5x + 6y + 7.5z = 87
x + y + z = 87
y = z + 5
4.5x + 6y + 7.5z = 489
x + y + z = 489
y = z + 5
4.5x + 6y + 7.5z = 87
x + y + z = 87
z = y + 5
4.5x + 6y + 7.5z = 489
