250 * $0.50 = ?

100+150 = 250 in all

Each bubble = 50 cents

250 * 0.5 = 125 dollars.

So it is equal to 125.00

Move the decimal point to the right one place

Harry made a mistake in his calculation. To fix the mistake, we need to correctly calculate the earnings for both Harriet and Harry.

Harriet blew 100 bubbles, and for each bubble she gets 50 cents. So, her earnings can be calculated by multiplying the number of bubbles by the amount earned per bubble: 100 bubbles * $0.50 = $50.

Similarly, Harry blew 150 bubbles, so his earnings can be calculated by multiplying the number of bubbles by the amount earned per bubble: 150 bubbles * $0.50 = $75.

Therefore, the total earnings for both Harriet and Harry can be calculated by adding their individual earnings: $50 + $75 = $125.

From the given information, we know that the total earnings were $12.50. To fix the mistake, Harry should divide this total by 100, as each cent is equal to 1/100th of a dollar: $12.50 รท 100 = $0.125.

Now, to determine Harry's mistake, we need to compare his calculated earnings ($0.125) to the actual earnings ($75). The mistake Harry made was that he used the wrong conversion factor when converting cents to dollars.

To fix the mistake, Harry should have divided the total earnings by 100 (since there are 100 cents in a dollar), rather than multiplying by 100.
