Final answer:
The price per pizza dough is $1.33.
Step-by-step explanation:
To find the price per pizza dough, we need to divide the total cost by the number of pizza doughs.
In this case, Jacob pays $20 for 15 pizza doughs. So, the price per pizza dough is $20 ÷ 15 = $1.33 (rounded to two decimal places).
