Answer 1

The answer is b.   You have to multiply 1.99 by 2 and 1.50 by 2.  Then you add those together. You subtract that price from 20.

Answer 2

Step 1: Add the price of a muffin to the price of a cup of milk.
Step 2: Multiply that total by 2.
Step 3: Add the tip to the final total for all the items.
Step 4: Subtract the total amount with tip from $20.

1.99+1.50=3,49
3.49 x 2=6.98
6.98+1.40=8.38
20-8.38=$11.62
