Ruby plans to make 3 quilts per month until she makes 15 quilts. she figures this will take 1/5 month. which is not a reason why this conclusion is wrong?
a) in 1/5 month, ruby would make fewer than 3 quilts.
b)dividing 3 by 15 does equal 1/5, but the unit is not months.
c)she should have multiplied 15 by 3 instead of dividing.
d)if ruby makes more than 3 quilts, the time will be more than 1 month.

c)She should have multiplied 15 by 3 instead of dividing.

Step-by-step explanation:

Number of quilts Ruby plan to make in one month= 3

which means if Ruby makes more than 3 quilts, the time will be more than 1 month.

To find the number of months to make 15 quilts, she need to divide 15 by 3

Thus, the number of months to make 15 quilts=5

Her answer was 1/5 which was absolutely wrong as if she is making 3 quilt in 1 month then in 1/5  month she would make fewer than 3 quilts.

She divides 3 by 15 instead of 15 by 3, thus but the unit is quilts not months.

Thus the only wrong option is c)She should have multiplied 15 by 3 instead of dividing.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
