Answer:
He will spend $560 in 8 weeks
Step-by-step explanation:
So 260 for every 3 weeks how much will he make in 8 weeks
so 240+ 240
cause he makes 240 every 3 weeks
so he will make 480 in 6 weeks.
then to get how much he makes in 1 week you divide 240 into 3
so 240 divided by 3 equals 80 So he makes 80 in 1 week.
So 240+240+80=560
So he make $560 in 8 weeks
1 bag per 5 minutes.
If you divide 15(total amount of min) by 3(bags of popcorn you popped) you will see you popped 1 bag per 5 minutes.
Now its say per minutes, then, you will have to say 1/5 bag per minutes.
The last choice is the reason, but to add to this, you are taking a value and breaking it into groups of 100( which is 10 groups of 10). Each place value in our decimal system naturally is based on a system of tens! Dividing by 100, is 2 groups of tens (2 decimal moves).
