A display for rolls of tape indicates that each roll contains 150 yards of tape. If the actual length of tape can vary by 2.5% of that amount, what is the range for the length of the tape on a roll

[146.25, 153.75] yards

Step-by-step explanation:

2.5% of 150 yards is ...

0.025 * 150 yd = 3.75 yd

This amount can be added or subtracted from the nominal length, so the range of lengths is ...

from 150 yd - 3.75 yd = 146.25 yd

to 150 yd + 3.75 yd = 153.75 yd
