Answer:
Price of Caleb's groceries before tax= $6.4
Step-by-step explanation:
Let price of groceries before tax be = $ 
Sales tax % = 2.5%
Sales tax applied = 
Actual sales tax paid = $1.60

Multiplying both sides by 100.


Dividing both sides by 25.


∴ Price of groceries before tax= $6.4
Price of the dining set = $785
Sales Tax = 7% of $785
Sales Tax = 0.07 x 785
Sales Tax = $54.95
Total price = $785 + $54.95 = $839.95
