Eliza bought 2 2/4 yards of fabric. She cut off 3/4 yards to make an art project. What fraction offabric is left?

7/4 or 1 3/4

Step-by-step explanation:

Think of 2 2/4 to be 10/4 because you need to multiply the 2 to the 4 which makes 8 and then add 2 to get 10/4.

When you get 10/4 subtract it with 3/4 to get 7/4.

You can leave it as 7/4 or 1 3/4.

Part a : Slope is 40 and it interpret the rate of increase of balance in dollars in the account per day.

Part b :  y - 720 = 40(x - 3) ... Point-slope form. 40x - y +600 = 0 ... Standard form. g(x) = 40x + 600 ... Slope-intercept form.

Part c : $880

Step-by-step explanation:

The table of values represents a linear function g(x), where x is the number of days that have passed and g(x) is the balance in the bank account:

x  g(x)

0 $600

3 $720

6 $840

Part a : Therefore, the slope of the function will be and it interprets the rate of increase of balance in dollars in the account per day.

Part b : If we denote g(x) = y, then the equation that models the table will be

⇒ y - 720 = 40(x - 3) (1) Point-slope form.

⇒ 40x - y +600 = 0 (2) Standard form.

⇒ y = 40x + 600

⇒ g(x) = 40x + 600 (3) Slope-intercept form.

Part c : From equation (3), the balance in the account after 7 days will be

g(7) = 40(7) + 600 = 280 + 600 = 880 dollars. (Answer)
