Mina spends $5 for her lunch and $2 for breakfast each day Monday through Friday. Use the associate property to find how much money she spends on lunch and breakfast for 4 weeks

Mina spends $80 for her lunch and breakfast for 4 weeks.

Curious how the AI robot tutor got its wrong answer this time.

real solution:
amount spent per day = $5 + $2 = $7
so for 1 week = 5(7) = $35
so in 4 weeks = 4(35) = $140
