Answer:
1. mean=1.5, median=1.7, mode is 1.8
2. mean=102,median=134, mode=no mode
3. mean=1885,median=2300, mode=2300
Step-by-step explanation:
They are indeed equivalent.
The ratios can be set up as 6/8 and 18/24.
Once simplified, both of these ratios become 3/4, and are therefore equivalent.
$15 - $8 = $7.
$7 / 2 = $3.50
spends $3.50 on each card.
