It uses a mix of Bluetooth and RF to combine the convenience of wireless power with the security of a wireless network. If it all pans out, WattUp could juice up your phone from up to 20 feet (6.1 meters) away. The heart of WattUp is a hub thatâs basically a powerful RF transmitter station. Devices that want to receive power from the hub announce their presence via Bluetooth 4.0. WattUp then uses that connection to direct the wireless power signal to the device.
Last year, the cost of lunch for elementary and high school students went up 50 cents to between $2.50 and $2.75 to make up for increasing costs. Sales dropped by 10 percent. The same thing happened across the nation as school lunch prices increased. A Government Accountability Office study found 1.2 million fewer students across the country bought school lunches between the 2010-11 and 2012-13 school years.
If a parent meets these income levels, the lunch is either free or less than the standard price. As of 2017, if your family income was between $31,590 and $44,955, a lunch will be less than $0.40. If the income is below $28,655, the lunch may be free. According to SchoolNutrition.org, the average school meal prices across the country widely vary. At an elementary school, the costs average out to about $2.34, while a middle school has a $2.54 average. A high school can cost $2.60 per lunch on average. ATTN.com created an informative infographic showing what the average student pays per state. According to this infographic, the costs were as little as $0 in West Virginia, District of Columbia, Alaska and West Virginia, while some states were close to $3; however, most states were in the $2.20 to $2.50 range.
