Harry's mother makes cakes for a local restaurant. she buys flour and sugar in large amounts. she has 157.86 pound of flour and 82.69 pound of sugar. if she uses 15 pounds of flour and 8 pounds of sugar each day, for about how many days will the flour last?

The flour will last for about 11 days.

Step-by-step explanation:

Suppose, the flour will last for   days.

She uses 15 pounds of flour each day. So, the total amount of flour used in days pounds.

Given that, she has 157.86 pound of flour. So, the equation will be......

Thus, the flour will last for about 11 days.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

what are the
