Final answer:
Jade can buy a maximum of 6 magazines in a week.
Step-by-step explanation:
To find the maximum number of magazines Jade can buy in a week, we need to divide her budget by the price of each magazine. The price of a magazine is $4 each, and Jade's budget is $24.
Therefore, the maximum number of magazines Jade can buy in a week is $24 / $4 = 6 magazines.
