Ruth's brother just went away to college this fall and had to buy his own laundry soap and fabric softener.The laundry soap was twice the cost of the fabric softener. the total of the two items was $7.47. how much did the laundry soap and the fabric softener cost individually?
I don't understand
x + 2x = 7.47
3x = 7.47
x = 2.49
2C+C=7.47
Cost favric softner=2.49
cost soap=4.98
Bobpursley gave you the answer.
how did you come up with the answer
I need to do the work on how I got the answer
What don't you understand about the problems and solutions we posted?
Mehh knows what's up
Thx
To solve this problem, let's assume the cost of fabric softener is x dollars.
Since the laundry soap is twice the cost of the fabric softener, we can say that the cost of the laundry soap is 2x dollars.
According to the given information, the total cost of both items is $7.47.
So, we can write the equation:
x (cost of fabric softener) + 2x (cost of laundry soap) = $7.47
Combining like terms:
3x = $7.47
To find the value of x, we can divide both sides of the equation by 3:
x = $7.47 / 3
Simplifying:
x ≈ $2.49
Therefore, the fabric softener costs approximately $2.49.
Since the laundry soap is twice the cost of the fabric softener, we can calculate its cost:
2x ≈ 2 * $2.49 ≈ $4.98
Thus, the laundry soap costs approximately $4.98.
To summarize:
The fabric softener costs approximately $2.49, and the laundry soap costs approximately $4.98.
