¢ · We write cents with the ¢ symbol, like 25¢. The $ symbol is for dollars.
0.52 · 52 cents is 52 hundredths of a dollar, written $0.52.
34 · 3 dimes are 30¢, and 4 pennies add 4¢, giving 34¢.
25¢ · A quarter is worth 25¢, the same as 25 pennies.
$2.95 · Bills give $2, quarters give 75¢, dimes give 20¢: $2.95 in total.
نادرست · 2 quarters are 50¢, and 50 - 40 = 10, so the change is 10¢, not 5¢.
35¢ · $1 is 100¢, and 100 - 65 = 35, so the change is 35¢.
20¢ · 2 quarters make 50¢. Take away the 30¢ cost: 50¢ − 30¢ = 20¢ change.
5 · 2 quarters make 50¢. Take away the 45¢ cost: 50¢ − 45¢ = 5¢ change.
She actually has 85¢, not 100¢ · 3 quarters make 75¢, plus a dime makes 85¢. That's not 100¢, so Zoe's total was wrong.
