Ø+T, let's knock this out. Here are the equations for each situation: 2. Step 1: Identify the knowns and unknowns. The cost of one can of coke is R x. You buy three cans, so the total cost of coke is 3x. You pay with R10 and receive R 2.20 change. Step 2: Formulate the equation. The amount paid minus the total cost of the items equals the change received. 10 - 3x = 2.20 The equation is 10 - 3x = 2.20. 3. Step 1: Identify the knowns and unknowns. The cost for four adults is R148. Let y be the cost for one adult. Step 2: Formulate the equation. The cost for four adults is 4 times the cost for one adult. 4y = 148 The equation is 4y = 148. 4. Step 1: Identify the knowns and unknowns. The cost of one metre of material is R x. You want to find the cost of 8 metres, which is 8x. It is given that 8 metres cost R116. Step 2: Formulate the equation. The total cost of 8 metres is equal to R116. 8x = 116 The equation is 8x = 116. 5. Step 1: Identify the knowns and unknowns. Let k be the exchange rate, representing how many Malawian Kwacha you get for one Rand. If you have R550, you get 11 550 Kwacha. Step 2: Formulate the equation. The total Kwacha received is the amount of Rand multiplied by the exchange rate. 550k = 11550 The equation is 550k = 11550. Send me the next one 📸
