A bike and skate shop rents bike for $21 per day and pairs of skates for $20 per day. To remain viable, the shop needs to make a
t least $362 per day from bike and skate rentals combined. If they rent twice as many bikes as they do pairs of skates, what is the least number of pairs of skates they need to rent each day to make their minimum?
You basically multiply the number outside the parentheses by everything inside. So 2 × 6x = 12x, 2 × 5 = 10, 2 × 2y = 4y. So your answer is 2(6x + 5 + 2y).
