Answer:
$ 2.98
Explanation:
Total amount spent by Mila equals $50.86
She bought 5 yards of fabric at $8.98 per yard. Hence, the total amount she spent on fabric is 8.98 × 5 = $44.9
It should be noted that since she bought only 2 kinds of things, this mean that Amount spent of fabric + Amount spent on thread = $50.86
Amount spent on thread = $50.86 - Amount spent on fabrics.
Amount spent on thread = $50.86 - $44.9 = $5.96
This is the total amount spent on thread.
But the question asks amount spent on one spool of thread. Since 2 spools would cost $5.96, one spool would cost $5.96 ÷ 2 = $2.98
