this month?

Respuesta :

Answer:

Nicole spent $42

Step-by-step explanation:

30=100%

140/100=x/30 (proportion) (cross multiply)

100x=4200

x=42

Answer:[tex]\\[/tex] (a) X = $30 + 40% of $30

[tex]\\[/tex]it could also be written as ; X = 140% of $30

[tex]\\[/tex]= $ 42

Step-by-step explanation:

[tex]\\[/tex]Amount spent last month = $30

[tex]\\[/tex]Let the amount spent this month be x,

[tex]\\[/tex]Then , x = 140% of $30

[tex]\\[/tex]x = 140/100 X 30

[tex]\\[/tex]x = $42
