Answer:
$1628
Step-by-step explanation:
A laptop computer was marked up 100% from an original cost of $740.
Marked up price = 100% of $740
= $740
Current price of the Laptop = Initial price of the Laptop + Marked up price
= $740 + $740
= $1480
Last Friday, Judy bought the laptop computer and paid an additional 10% in sales tax. What was her total cost?
Sales tax = 10% of the cost of laptop
= 10% × $1480
Sales tax = $148
Judy's total cost = Price of the Laptop + Sales tax
= $1480 + $148
= $1628
37+53=90 so 180-90=90
x=90
x= 180-(37+53)
x= 90 ✅

Now, you color the line so that all values that are less than 6 are shaded, so you put an open circle at 6 since it's not included and then you shade everything to the left.
Answer:
Just match values.
