Answer:
Ted can buy the three books for $16.99 each
Step-by-step explanation:
The two books will cost a total of $59.90
$29.95 • 2 = $59.90 <u>OR</u> $29.95 + $29.95 = $59.90
The headphones and portable speaker will cost a total of $60.94
$29.99 + $30.95 = $60.94
The MP3 player and gift card will cost a total of $55.99
$35.99 + $20.00 = $55.99
The three books will cost a total of $50.97
$16.99 • 3 = $50.97 <u>OR</u> $16.99 + $16.99 + $16.99 = $50.97
