Ann makes (4x+3) an hour and she worked (2x-1) hours this week. Write an expression that represents the amount of money Ann earned this week.

Amount of money Ann earned this week = Amount of money earned in 1hour * Number of Hours she worked

Amount of money Ann earned this week = (4x + 3) * (2x - 1)

= (4x + 3) (2x - 1)

{Draw lines like rainbows to let yourself know which numbers to multiply by}

= (4x * 2x) + [4x * (-1) ] + (3 * 2x) + [3 * (-1) ]

{Always remember to put in the negative signs if the number if negative}

= 6x^2 + (-4x) + 6x + (-3)

= 6x^2 - 4x + 6x - 3

{Simplify}

= 6x^2 + 2x - 3
