Think first$1.79 each, or 3 for $5.00
Granola bars are $1.79 each, or 3 for $5.00. Is 3 for $5.00 a saving?
Decide first, then press Next. Compare the same number of items both ways.
A plain tag, $1.79 for one granola bar, beside an orange tag, 3 for $5.00. Then three items each marked $1.79 and the line 3 × $1.79 = $5.37. Then $5.37 − $5.00 = $0.37 less with the deal, and $5.00 ÷ 3 is about $1.67 each. The last step asks about sports drinks at $2.29 or 4 for $10.00.

The big idea
Check a multi-buy: multiply the single price, then compare with the deal.
Same number, both ways
The deal is for 3, so price 3 the regular way: 3 × $1.79 = $5.37. Then compare.
- 3 singles$5.37
- the deal$5.00
- saved$0.37
Easy to get wrongSome deals cost more. 4 for $10.00 is $2.50 each; if one costs $2.29, the deal is worse.
Key word
- multi-buy
- a deal for several items at one price, such as 3 for $5.00
