Ian used a grocery delivery app to have his groceries delivered. His original order was $25 before delivery and tip. He noticed that 3 items changed on his order. A $0.99 can of tomatoes was replaced by a $2.20 can of tomatoes, his $1.00 lettuce was replaced with $1.75 head of lettuce and his $1.96 celery was replaced with celery that cost $2.00. Delivery and tip came to a total of $8.00. How much is his new bill now, with the food substitutes and delivery/tip?
Let's think step by step.

He ordered a can of tomatoes for $0.

99 but they subbed with one that cost $2.

20 for a difference of 2.

20 -.

99 = $1.

21.

He ordered lettuce for $1.

00 but they subbed with one that cost $1.

75 for a difference of 1.

75 - 1.

00 = $0.

His celery for $1.

96 but they subbed with one that cost $2.

00 for a difference of 2.

00 - 1.

96 = $0.

04.

That's an additional charge of 1.

21 +.

75 +.

04 = $2.

00 in groceries.

His additional charges of $2.

00 and the delivery / tip of $8.

00 add 2 + 8 = $10.

00 to the order.

His original order was $25 and they added $10.

00 so his new order is 25 + 10 = $35.

00.
