Answer:
a) Number of laundry he can do with this box = 78 laundries.
b) Price he paying for each load = 0.256 $
Explanation:
Total scoop contained in detergent box = 195 scoops.
Scoops used by each load of laundry = scoops = 2.5 scoops
Number of laundry he can do with this box = 195/2.5 = 78 laundries.
Price of detergent box = 19.99 $
Price he paying for each load = Total price/ Number of loads
= 19.99/78
= 0.256 $
The unknown number is 108.
Step-by-step explanation:
Step 1:
Assume the unknown number is x.
We create an equation from the given data.
One-fourth of the number is , seven less than one-fourth of the number is
. Two times the quantity of seven less than one-fourth of a number is therefore
.
One-third of the number is , four more than one-third of the number is given by
.
Step 2:
We substitute both equations to determine the value of x.
So the unknown number is 108.
