Question

Elizabeth bought lemons (l) and apples (a). Each apple costs 35¢ and each lemon costs 15¢. All together, she bought 17 lemons and apples for $3.95. Which system can be used to determine how many of each she bought?

Answer 1

Explanation:

Let the number of apples be a and lemons be l . Then ,

=> a + l = 17

Also ,

=> 35a + 15l = $ 3.95

Answer 2

Explanation:

Given:

• Lemons - l and apples - a
• a = 35¢, l = 15¢
• Number of apples and lemons = 17
• Cost of lemons and apples = $3.95 = 395¢

System as per question:

• a + l = 17
• 35a + 15l = 395

Or

• a + l = 17
• 0.35a + 0.15l = 3.95
