Question

9. Royanne determined that it cost her $.75 a day to make her own lunch

for school. If she ate in the cafeteria, lunch would cost $2.25. In five days,
how much money would Royanne save by bringing her own lunch to
school?
O $5.50
O $7.50
$9.50

Answer 1

She would save $7.50.
If you calculate how much money it would cost her to make her own lunch times the five days which you will get…
0.75 *5= $3.75
And then calculate how much money it would cost her to eat in the cafeteria times the five days..
$2.25*5=11.25
Now you want to subtract the amount she makes her own lunch and the amount that she would eat in the cafeteria so…
11.25 - 3.75 = $7.50

So in the end she would save $7.50 if she was to bring her own lunch to school.

I hope this helps, have a good day! :D
