A baby-sitter charges $3.00 for the first hour and $1.25 for each additional hour or part of an hour. How much will she receive for 4 1/2 hours of baby-sitting?

Whit h equation best represents this situation the number 98 increased by an unknown number equal to 120

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
