Answer:
$35 - 3b is greater or equal to $10
Step-by-step explanation:
Remember that:
Dollars spent on an item = (cost of one item)*(number of items), so –
Dollars spent on comic books = $3b
“Tracy has $35 to buy comic books and to pay for a movie ticket” means
(Money spent on comic books) + (money spent on movie ticket) ≤ $35
(Money spent on comic books + $10 ≤ $35
$3b + $10 ≤ $35 [just substituting values]
Now, we must modify the inequality, so remember the rules –
$35 ≥ $3b + $10 [reverse right-to-left reverses the sense of the inequality;
$35 is greater or equal to the total amount Tracy can spend]
$35 - $3b ≥ $10 [subtract positive 3b from both sides
keeps the sense of the inequality]
