If you wish to<u> mentally estimate</u> the <u>total cost</u> of items, <u>rounding </u>off the items to the<u> nearest half dollar</u>, then you have to consider all five items separately.
Five items cost $1.85, $.98, $3.49, $9.78, and $6.18.
1. $1.85≈$2;
2. $0.98≈$1;
3. $3.49≈$3.50;
4. $9.78≈$10;
5. $6.18≈$6.
Then the total cost is
$2 + $1 + $3.50 + $10 + $6 =$22.50.

Step-by-step explanation:
Answer:
14 inch
Step-by-step explanation:
A = πr^2
153.94 = π * r^2
153.94/π = 49.001 = r^2
√49.001 = r = 7
radius * 2 = diameter
7 * 2 = 14 inch diameter
Answer:
The unit price is 4.15 dollars per gallon
Step-by-step explanation:
- Yolanda buys 5.8 gallons of gas for $24.07
- We need to find the unit price in dollars per gallon
- Unit price means the price of each gallon
∵ The number of gallons = 5.8 gallons
∵ The price of the gallons = $24.07
∵ The unit price = the amount of money ÷ number of gallons
∴ The unit price = 24.07 ÷ 5.8
∴ The unit price = 4.15 dollars per gallon
* <em>The unit price is 4.15 dollars per gallon</em>
