a starbucks employee opened a new box of straws. The first day, the employee used 30 straws from the box. The second day, the employee used 15% of the remaining straws in the box. A total of 90 straws were used on the second day. What was the original number of straws in the box before any straws were used?

630 straws were in the box before any was used.

Step-by-step explanation:

So we know that 15% were used out of the remaining straws after 30 was used.

So if 630 straws were there in total then we will substrate 30 from the total 630 and multiply the rest by 15% to find out if it equals 90.

630 - 30=600

600 * 15%=?

600 * 0.15=90

So it makes sense that 630 straws were there in total.
