Answer 1

To find the total cost of the toys and games that Liam bought, we first calculate the cost for each type of item.

1. Cost of toy cars:

   • Liam buys 5 toy cars at $3.75 each.
   • Total cost for toy cars = 5 × $3.75 = $18.75.

2. Cost of board games:

   • Liam buys 4 board games at $6.50 each.
   • Total cost for board games = 4 × $6.50 = $26.00.

3. Total cost:

   • Total cost = Total cost of toy cars + Total cost of board games
   • Total cost = $18.75 + $26.00 = $44.75.

Now, we need to estimate the total cost by rounding the prices to the nearest dollar:

• Rounded cost of toy car: $3.75 rounds to $4.
• Rounded cost of board game: $6.50 rounds to $7.

Now we recalculate the total with the rounded values:

1. Estimated cost of toy cars:

   • Estimated cost for toy cars = 5 × $4 = $20.

2. Estimated cost of board games:

   • Estimated cost for board games = 4 × $7 = $28.

3. Estimated total cost:

   • Estimated total cost = Estimated cost of toy cars + Estimated cost of board games
   • Estimated total cost = $20 + $28 = $48.

Therefore, the estimated total cost of the toys and games is $48.
