Mrs. Jackson bought 31 calculators for her
students to use at school. Each calculator costs]
$1.89, including tax/ How much change she will
get back if she gives the clerk a $100 bill?.

67.11

Step-by-step explanation:

you just add the amount with all calculators and then subtract your answer with 100

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
