Alex17521 [72]

Answer:

Total cost = <em>$</em> 4.55

Step-by-step explanation:

2(8a + 5b) -(2a + 3b)

<em>Part A: Simplify the expression shown above</em>

Exapanding the brackets;

16a + 10b - 2a - 3b

Collecting like terms;

16a - 2a + 10b - 3b

14a + 7b

<em>Part B: If a represents apples that cost $0.25 each and b represents bananas that cost SO. 15 each, what is the total cost based on the expression above?</em>

a = 0.25

b = 0.15

14a + 7b

Inserting the values into the equation;

14 (0.25) + 7(0.15)

Total cost = <em>$</em> 4.55
