Question

Chance has $2 in quarters. Blake has $5 in dollar coins. Whose coins have the greatest mass? Explain.

Answer 1

Chance coins have a greater mass because the coin mass of a quarter is 5.67 you multiply by 8, which is the number of quaters you have and you get 45.36 grams. if you do the same with the dollar coins, meaning you multiply the the mass by the number of coins, you should get 40.5 grams.

Answer 2

The mass of Chance's coins if greater then Blake's

$2 in quarters is 8 quarters because every dollar is 4 quarters
so 8×5.67 is 45.36
$5 In dollar coins is 5 coins
so 5×8.1 which is 40.5

45.36 (Chance's coins) is greater than 40.5 (Blake's coins)
