You have 1 case of soap bars and there are 150 bars in a case you use 300 bars of soap per day how many cases do you need to order to have enough for 7

13 cases

Step-by-step explanation:

we know that

You have 1 case of soap bars

There are 150 bars in a case

You use 300 bars of soap per day > 2 cases per day

using proportion

Find how many cases do you need to order to have enough for 7 days

Let

x >the number of cases

2/1=x/7

x=2*7=14 cases

but remember that you have 1 case

so

you needed 14-1=13 cases

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
