Question 5 Megan spent one-fourth as much as Hannah, who spent d dollars. Emily spent ten dollars more than Megan. Kyle spent three dollars less than Emily. Which expression represents the amount Kyle spent?

Respuesta :

Hannah spent "d" dollars

Megan spent 1/4 as much as Hannah, that is "1/4d"

Emilly spent 10 dollars more than Megan, so to what Megan spent, you have to add 10, "1/4d+10"

And Kyle spent three dollars less than Emily, this means that to the expression corresponding to Emily's spending, you have to subtract 3, "(1/4d+10)-3" → you can simplify it as "1/4d+7"

So, the expression that represents Kyle's expenses is

[tex]\frac{1}{4}d+7[/tex]
