Answer:
1 pint is 0.85 dollars or 85 cents
Step-by-step explanation:
1 pint= 0.125 gal, so 8 pints= 1 gal
27.20/4 is 6.8 (for 1 gal)
6.8/8 is 0.85 (for 1 pint)
85 cents per pint
Let x be the cost of gum 20 years ago.
3x - 3 = 75
3x = 78
X = 78/3
X = 26.
So the write answer is A) 3x - 3 = 75.
Step-by-step explanation:
∑⁴ₙ₌₁ -144 (½)ⁿ⁻¹
This is a finite geometric series with n = 4, a₁ = -144, and r = ½.
S = a₁ (1 − rⁿ) / (1 − r)
S = -144 (1 − (½)⁴) / (1 − ½)
S = -270
If you wanted to find the infinite sum (n = ∞):
S = a₁ / (1 − r)
S = -144 / (1 − ½)
S = -288
