Question

A dozen donuts cost $6 at Betty’s bakery. They cost $.80 each at the grocery store. If you only want 8 donuts, where should you buy them

Answer 1

You should buy 8 donuts at Betty's bakery

Explanation:

It is given that 12 donuts cost $6 at Betty's bakery.

Each donut costs $0.80 at the grocery store.

Using this information, we can find the unit rate of each store and figure out where you should buy your donuts.

Unit rate = (total cost/number of items)

Betty's Bakery -
`(6)/(12)` = $0.50 per donut

Grocery store - $0.80 per donut

Now we can multiply the unit rate by 8 donuts to see which store has the lesser price:

Betty's Bakery - $0.50*8=$4.00 for 8 donuts

Grocery store - $0.80*8=$6.40 for 8 donuts

It costs $2.40 more to buy 8 donuts at the grocery store than at Betty's bakery.

Buy from Betty's bakery.
