Q2/ Maria has an online shop where she sells hand made paintings and
cards. She sells the painting for 50 and the card for 20. It takes her 2 hours
to complete 1 painting and 45 minutes to make a single card. She also has
a day job and makes paintings and cards in her free time. She cannot spend
more than 15 hours a week to make paintings and cards. Additionally, she
should make not more than 10 paintings and cards per week.
She makes a profit of 25 on painting and 15 on each card. How many
paintings and cards should she make each week to maximize her profit.
