Question

walmart sells thermometer for $2 and heat packs for $2 walmarts total sales are $1134. customers bought six times as many thermometers than heat packs. how many of each did walmart sell

Answer 1

Since both products cost the same each ($2), we can consider how many multiples of seven (six thermometers for each heat pack) would make up the 567 items sold. ($1134 total sales divided by $2 per item)

 

567/7 = 81.  There were 81 heat packs sold.

6 * 81 = 486.  There were 486 thermometers sold.

 

Checking our math: 81 + 486 = 567.  567 * $2  = $1134.
