Final answer:
The new container holds c) 66.25 fluid ounces of laundry soap.
Step-by-step explanation:
To find out how much the new container holds, we need to increase the original amount by 25%. The original container held 53 fluid ounces, so we can find the amount in the new container by multiplying 53 by 1.25 (1 + 0.25). This gives us:
New container size = 53 * 1.25 = 66.25 fluid ounces
So, the new container holds 66.25 fluid ounces of laundry soap.
