Abby is trying to pay off her debt. She owes $422 to her bank. In may she paid $76, but had to borrow an additional $135. In June she paid $45 and borrowed $110. The bank also charged her $58 in interest. How much did she owe at the end of June. Do this quickly

Hi! Your answer to this problem..

Step by Step Explanation: Subtract 422 with 76, add 135, subtract 45, add 110, and lastly add 58.

Subtract 422 with 76, 422-76=366.

Add 366 with 135, answer will be 501.

Subtract 501 with 45 since she paid $45. 501-45=456.

Add 456 with 110 and that would be 566.

For the last step add 58 to find the answer and you would get 624.

Final Result: 624.

i can answer this question sweetie!

step-by-step explanation:

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
