¿cual ea el pasatiempo favorite de tu sobrino?

El pasatiempo favorito de mi sobrino es cuando se inscribió en el fútbol y ganó su primer juego.

$3.4

Step-by-step explanation:

Total amount spent by Mila equals $71.05

She bought 5 yards of fabric at $12.85 per yard. Hence, the total amount she spent on fabric is 12.85 × 5 = $64.25

It should be noted that since she bought only 2 kinds of things, this mean that Amount spent of fabric + Amount spent on thread = $71.05

Amount spent on thread = $71.05 - Amount spent on fabrics.

Amount spent on thread = $71.05 - $64.25 = $6.8

This is the total amount spent on thread.

But the question asks amount spent on one spool of thread. Since 2 spools would cost $6.8, one spool would cost $6.8 ÷ 2 = $3.4
