Ruth's Brother went away to his college this fall and had to buy his own laundry soap and fabric softener. The laundry soap costs twice as the cost of the fabric softener. The Total of the 2 items was $7.47. How much did the laundry soap and fabric softener cost individually? PLEASE HELP! I don't get this and it's due very soon! D:
x + 2x = 7.47
3x = 7.47
x = 2.49
The fabric softener costs $2.49.
tysm Mrs. Sue!
To solve this problem, we can use algebra. Let's assume that the cost of the fabric softener is represented by the variable 'x'. According to the problem, the laundry soap costs twice as much as the fabric softener, so we can represent the cost of the laundry soap as '2x'.
The problem also states that the total cost of the two items is $7.47. Therefore, we can create the equation:
x + 2x = 7.47
Combining like terms:
3x = 7.47
To solve for x, we need to isolate the variable. We can do this by dividing both sides of the equation by 3:
x = 7.47 / 3
Calculating this, we find that:
x ≈ 2.49
So, the cost of the fabric softener is approximately $2.49.
To find the cost of the laundry soap, we can substitute the value of x into the equation:
2x = 2 * 2.49
Calculating this, we find that:
2x ≈ 4.98
So, the cost of the laundry soap is approximately $4.98.
Therefore, the fabric softener costs approximately $2.49 and the laundry soap costs approximately $4.98 individually.
