B) $300
C) $360
D) $420
E) $480

Answer 1

The total cost of 48 cans of tennis balls and 12 boxes of golf balls is $390

Step-by-step explanation:

To calculate the total cost, we need to determine the cost of the tennis balls and the golf balls separately and then add them together.

The cost for 12 cans of tennis balls is $30. If a coach orders 48 cans, we can calculate the cost by multiplying the cost for 12 cans by 4: $30 x 4 = $120.

The cost for 2 boxes of golf balls is $45. If a coach orders 12 boxes, we can calculate the cost by multiplying the cost for 2 boxes by 6: $45 x 6 = $270.

Finally, we can add the cost of the tennis balls ($120) and the cost of the golf balls ($270) together: $120 + $270 = $390.

Therefore, the total cost is $390.
