  2. Anwen bought some chocolate bars costing 50p each and some bananas costing 30p each. The total cost was £5.80. Over the next few days she ate 5 of the chocolate bars and 1/3 of the bananas. What she had left was worth £2.70. How many chocolate bars and bananas did she buy ? Helping hand • Let x be the number of chocolate bars and y be the number of bananas. Set up an equation for what she bought. • Set up a similar equation for how much she had left • Solve these equations

  3. Answer Let x be the no. chocolate bars and y be the no. bananas 50x + 30y = 580 50(x-5) + 30((2/3)y) = 270 50x - 250+ 20y = 270 50x + 20y = 520 5x + 3y = 58 5x + 2y = 52 y = 6 5x + 3(6) = 58 5x + 18 = 58 5x = 40 x = 8 Anwen bought 8 chocolate bars and 6 bananas
