Marie is planning to buy a new cash register for her bakery that costs $1040. Every day Marie sells 40 loaves of bread for $2 each and 6 cakes for $12 each. She has to pay $20 each day for rent and $2 each day for electricity. How many days' worth of profits will it take for Marie to pay for the cash register?
First figure out how much money Marie makes from selling bread each day by multiplying the number of loaves sold by the price per loaf: 40 loaves * $2/loaf = $<<40*2=80>>80
Next figure out how much money Marie makes from selling cakes each day by multiplying the number of cakes sold by the price per cake: 6 cakes * $12/cake = $<<6*12=72>>72
Now add the money from selling the bread to the money from selling the cakes to find Marie's total daily income: $80 + $72 = $<<80+72=152>>152
Next subtract Marie's daily expenses from her daily income to find her daily profit: $152 - $20 - $2 = $<<152-20-2=130>>130
Finally, divide the price of the cash register by Marie's daily profit to find how many days' profits she needs to pay for it: $1040 / $130 = <<1040/130=8>>8
