Pani says she should get $3 discount on the price of each shirt and $3 discount on the price of each pair of jeans. Part 1 write and simplify an expression to find the pint she would pay if this is true. Part 2 if you were the shop owner, how would change the sign? Please answer
Part 1: To write and simplify an expression to find the price Pani would pay, given a $3 discount on each shirt and a $3 discount on each pair of jeans, we can use the following expression:
Let's say the price of each shirt is S and the price of each pair of jeans is J.
The total discount on shirts would be the number of shirts multiplied by $3, which is 3S. Similarly, the total discount on jeans would be the number of jeans multiplied by $3, which is 3J.
Therefore, the expression to find the price Pani would pay, after applying these discounts, would be:
P = (S - 3S) + (J - 3J)
Simplifying the expression, we have:
P = S - 3S + J - 3J
P = -2S - 2J
So, the price Pani would pay can be represented by the expression -2S - 2J.
Part 2: If I were the shop owner and wanted to change the sign to give Pani the discounts, I would write the expression as a positive value.
In this case, I would change the expression -2S - 2J to 2S + 2J. By doing this, the negative discount is transformed into a positive discount.
