Answer:
$.56
Step-by-step explanation:
The first minute is .50 cents and the subtotal was 5.60. Subtract for the first minute to get the subtotal for 9 minutes.
(5.60-.50=5.10)
5.10 is the amount for 9 minutes so now we will divide to get the price for each minute.
(5.10÷9=.56)
This means each minute after the first minute is $.56 cents.

Answer:
$101.97
Step-by-step explanation:
Diameter of circular wooden deck = 30 ft
Radius of the deck = ½ of diameter = ½*30 = 15 ft
Area of deck = πr² = 3.14*15² = 706.5 ft²
1 gallon covers 250 ft² (1 gallon = 250 ft²)
Let x be the number of gallons that will cover 706.5 ft² of the deck
Thus:
1 gallon = 250 ft²
x = 706.5 ft²
Cross multiply
1*706.5 = 250*x
706.5/250 = x
2.826 = x
Number of gallons to cover the deck is approximately 3 gallons (approximated to nearest whole number). Since the we can't buy a gallon that is not full, we approximate to give us 3 gallons.
1 gallon cost $33.99 (1 gallon = $33.99)
3 gallons cost: 3*33.99 = $101.97
