Frank had to make 200 toy cars. He made 8 toy cars each day from Monday to Friday and 15 each day on Saturday and Sunday. Starting on a Thursday, on which day of the week did Frank complete making all the toy cars?
70 per week ... 8*5 + 2*15
three Wednesdays from the start would be 210 cars
minus 8 on Wednesday ... finished 200 on a Tuesday
