Ivanna purchased a prepaid phone card for $30. Long distance calls cost 16 cents a minute using this card. Ivanna used her card only once to make a long
distance call. If the remaining credit on her card is $28.24, how many minutes did her call last?

11 Minutes

Step-by-step explanation:

$30 - $28.24 = $1.76

$1.76/ 0.16 Cents /minute =  11 Minutes

step-by-step explanation:

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
