Challenge Yourself Question 1 (p8):
Write down a word problem such that the equation to be formed for solving the problem is 5x + 4(x - 10) = 140

• Sandy bought 5 carrots at \$x and 4 lettuce at \$(x-10). She spent a total of \$140. How much did each carrot and lettuce cost respectively?
• Nina:
• Sam bought 5 apples and 4 oranges. The cost of an apple is \$10 more than the cost of an orange. Sam gave \$150 and received \$10 from the cashier.
