Answer:

41.

No, Amits reasoning is not correct. The problem used to represent the equation, (-5.75) × 7, was solved incorrectly. (-5.75) × 7 = (-40.25). We know this because a negative number times a positive number is always a negative number. So the correct answer for the change in Amits bank account is -40.25

47.

a- Ivan's expression: $4.25 + $1.25(m)

Vicky's expression: $5.75 + $0.75(m)

b- $4.25 + $1.25(m) + $5.75 + $0.75(m)

<em>[</em><em>add</em><em> </em><em>$</em><em>4.25</em><em> </em><em>+</em><em> </em><em>$</em><em>5.75</em><em>]</em>

$10.00 + $1.25(m) + $0.75(m)

<em>[</em><em>add</em><em> </em><em>$</em><em>1.25</em><em>(</em><em>m</em><em>)</em><em> </em><em>+</em><em> </em><em>$</em><em>0.7</em><em>5</em><em>(</em><em>m</em><em>)</em><em>]</em>

<em> </em><em> </em><em> </em><em> </em>$10.00 + $2.00(m)

c- $10.00 + $2.00(m)

d- $10.00 + $2.00(m)

<em>[</em><em>2</em><em> </em><em>÷</em><em> </em><em>2</em><em> </em><em>=</em><em> </em><em>1</em><em>]</em><em> </em><em> </em>

<em>[</em><em>1</em><em>0</em><em> </em><em>÷</em><em> </em><em>2</em><em> </em><em>=</em><em> </em><em>5</em><em>]</em>

e- 2(m + 5)
