Maria bought shoes for $40. Taxes are 7% and there is a 15% discount. What is her total cost?

31.2

Step-by-step explanation:

15+7 = 22

100-22 = 78

78% * 40

= 31.2

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

∞ this is your sign
