Total amount = 31.50×4/3
= 42$
original price of skirt = total - price of blous = 42-18 = 24$
The skirt was originally 24 dollars
Step-by-step explanation:
3/4 ( b+s) = 31.50
where b is the original price of the blouse and s is the original price of the skirt
b = 18
3/4 ( 18+s) = 31.50
Multiply each side by 4/3
4/3 * 3/4 ( 18+s) = 31.50 *4/3
18+s =42
Subtract 18 from each side
18+s-18 = 42-18
s =24
The skirt was originally 24 dollars
The original price of the skirt is $24
Step-by-step explanation:
The complete question is
Jade buys a blouse and a skirt for 3/4 of their original price. Jade pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt?
Let
x ----> the original price of the blouse
y ---> the original price of the skirt
we know that
Three fourth of the sum of the original price of the blouse and the original price of the skirt, must be equal to the total paid for the two items
so
The linear equation that represent this situation is
we have
----> given problem
substitute the value of x in the expression above and solve for y
Multiply by 4 both sides
therefore
The original price of the skirt is $24
