Since you are not given the following choices, by analyzing this series, it is a geometric progression because their common ratio is constant. Proofing that
4.8/(-3.2) = -1.5, also
-7.2/(4.8) = -1.5, and also
10.8/(-7.2) = -1.5
<h3>
Answer:</h3>
$20.55
<h3>
Step-by-step explanation:</h3>
(price last week) - 27% × (price last week) = $15 . . . . what the problem says
(price last week) × (1 - 0.27) = $15 . . . . factor out price
(price last week) = $15/0.73 . . . . . . . . . divide by the coefficient of price
(price last week) ≈ $20.55
His answer was wrong. The correct answer would be 129,000
Explain: 500 rounded to the nearest thousand would be 1000
But 499 rounded to the nearest thousand would not become 1000
Area of the trapezium = 1/2 (40 + 160) x 70
Area of the trapezium = 7000 ft²
One bag of fertilizer = 4000 ft²
Number of bags of fertilizer needed = 7000 ÷ 4000 = 1.75 bags.
Since only full bags of fertilizer can be bought, 2 bags of fertilizer are needed.
