rocco wants to use the rest of the money in his savings account ($192) to buy a set of golf irons that has an original price of $350. does rocco have enough money to buy the golf irons? explain. 

Answers

if the golf irons are on sale for less than $192 then yes he does but obviously if the irons aren't on sale then no Rocco does not have enough money tho but them.

Final answer:

Rocco does not have enough money to buy the golf irons because the difference between the original price and the money in his savings account is $158.

Explanation:

To determine if Rocco has enough money to buy the golf irons, we need to find the difference between the original price and the money in his savings account.

Difference = Original Price - Money in Savings Account

Difference = $350 - $192

Difference = $158

Rocco does not have enough money to buy the golf irons because the difference between the original price and the money in his savings account is $158.
