Question

10. Liliana makes and sell homemade bracelets. She made a profit of $75 last week. She donated some bracelets to charity. This week her profit was represented as -$50. Write a subtraction and addition expression to represent Liliana's total profit for two weeks combined.

Answer 1

75+(-50)=75-50

Explanation:

-let x be the profit made last week and y be the profit made this week.

-The two week profit/ loss is given as:

`Profit=x+y`

#We substitute actual values to calculate the profit/loss made:

`Profit=x+y\\\\=75+(-50)\\\\=75-50\\\\=\$25`

Hence, the two-week combined profit is $25.00
