Answer:
amount loaned at 8% interest is $11.60
Explanation:
given data
loan = $12,000
rate = 8% per year = 0.08
other rate = 18% per year = 0.18
interest receive = $1000
solution
we first consider here amount for loaned at 8% = x
so here amount for loaned at 18% will be = $12,000 - x
so we can say interest received equation will be here as
$1,000 = (0.08)x + (0.18)($12,000 - x)
solve it we get
x = $11.600
so amount loaned at 8% interest is $11.60
