Question

How much money did he spend?

Answer 1

He spent $6.80. Just multiply 4 by 1.7 since he bough 1.7lbs for $4 per lb

Answer 2

$6.80

Explanation:

Since salami costs $4/lb and he bought 1.7lbs you would need to multiply the amount of salami he bought by the cost (4x1.7=6.8) which would then give you the amount of money he spent on the salami that he bought.
