Three learners from Chris Hani Arts and Culture High School will represent the province in a national competition.Somila Tete (17) a Grade 11 learner, Sinalo Vokwana (16) and Yanga Jwaqa (16) – both in Grade 10, won a Step Up to a Start Up and Smart Bucks competition in the Western Cape. The competition is a financial literacy programme for children at high schools in disadvantaged areas. Tete said the organisers wanted them to come up with an idea that involves technology and would improve the economy.Yanga said their idea was inspired by a shopper they saw at a supermarket. The shopper had a lot of items in the trolley and when it was time to pay, the person did not have enough money and had to leave some of the items behind.“We saw the inconvenience it caused the customer and the others in the queue,” he said.Vokwana said they came up with the idea of what they call a Trolley Total.“Our idea is to have a scan in a trolley so that when one goes shopping they scan every item before they put it in a trolley so they know the total amount of items before going to the tills and if they can afford it,” he said.Tete said they told shoppers about their idea and asked what they thought and they all said it would be of great help. The idea came out tops in the provincial competition and are now at the nationals which started with a bootcamp on Monday 2 December. The winner was to be announced yesterday.
