There’s an invisible 1 in front of the minus sign and an invisible 1 in front of the variable.
-1(r+4)=-3 —> -1 times 1r = -1r. -1 times 4 = -4
Multiply inside the parentheses.
-1r-4=-3
Now add 4 to both sides.
-1r-4=-3
 +4=+4
-1r = 1
 Now divide
R= -1

Answer:
9 dollars
Step-by-step explanation:
Hello you did not provide the options for me to select from. But I have gone ahead to calculate how much jessica would pay for her cookie dough.
I used this formula to arrive at this answer.
Cost of dough = quantity x price per ounce
Quantity = 6 ounces
Price per ounce = 1.5 dollars
Cost of dough = 6 x 1.50
= $9
Jessica is going to pay 9 dollars for her cookie dough
