Question

A small box of pens cost $6. A large box of pens cost $8. The table shows the costs of buying certain numbers of boxes of pens. Which ordered pair represents the cost of 5 small boxes and 5 large boxes?

Answer 1

The total cost for 5 small boxes and 5 large boxes of pens is $70. The ordered pair representing the quantities of small and large boxes respectively is (5, 5).

Step-by-step explanation:

The subject of the question is mathematics, specifically, calculating the total cost of multiple items. To determine the cost of 5 small boxes and 5 large boxes of pens, we use the given prices: $6 for a small box and $8 for a large box. Multiplying each price by the number of boxes gives us the cost for each type:

• 5 small boxes × $6 per box = $30
• 5 large boxes × $8 per box = $40

Adding these two amounts gives us the total cost:

$30 (for small boxes) + $40 (for large boxes) = $70

Therefore, the ordered pair that represents the cost of 5 small boxes and 5 large boxes is (5, 5), with a total cost of $70.
