Select why this equation is true or false. 44 + 18 = 42 + 16

• False, because if 2 is subtracted from 44 to get 42 then, 42 and 18 would not equal 42 and 16.

• True, because if we compare 44 to 18 and 42 to 16 they are exactly the same distance apart on a number line.

• False, because if 2 is subtracted from 44 to get to 42 then 42 and 18 would not equal 42 and 16

• True, because both 44 minus 18 and 42 minus 16 result in the same answer of 58.

Ms. Esposito's family went to Disney.

Admission prices were $15 for each adult and $6 for children.

Parking was an additional $18.

If Ms. Esposito's family has 4 adults and 2 children, which equation could be used to find the total cost (t) of their trip?

• t = (4 x $15) + (2 x $6)

• t= (4 + $15) + (2 + $6)

• t= (4 + $15) + (2 + $6) + $18

• t= (4 x $15) + (2 x $6) + $18
