Ms. Edwards can spend, at most, $250 on new books for the school library. She will buy a reference book on birds for $30 and a reference book on the planets for $14.95. Let x represent the amount of money Ms. Edwards can spend on other books. Write an inequality that correctly describes this situation.

x ≤ 205.05

Step-by-step explanation:

x = dollar amt remaining for other books

30 + 14.95 + x ≤ 250

44.95 + x ≤ 250

x ≤ 205.05

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

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
