Answer:
$ 68
Step-by-step explanation:
Let original value of a single share to be $ x
For 17 shares, total value of shares will be $17x
After a decrease of $4 per share, new value of a share will be $ x-4
For 17 shares, total value of shares after decrease will be $ 17(x-4) = 17x-68
Total change in the value of her stock will be ; value of shares before decrease-value of shares after decrease
= 17x-(17x-68)
=17x-17x+68
=68
A. Length - 100 ft Width - 50 ft is the measurement of Tony's backyard.
Albert's Perimeter = 2(l+w) = 2(40+20) = 2(60) = 120 ft.
Tony's Perimeter = 120 ft * 2.5 = 300 ft
Tony's length = 40 ft * 2.5 = 100 ft
Tony's widht = 20 ft * 2.5 = 50 ft
To check tony's perimeter:
P = 2(l + w) = 2 (100 + 50) = 2 (150) = 300 ft.
Replace each letter with it's value, so:
= (5*-2) + (-3*2) + 3
= -10 -6 +3
= -13
