Let the number of CD's be x and total cost be y
y=7x-10
*the 7 comes from the price of each individual CD ($7)
*the 10 comes from the discount ($10)
6. $14*0.045= $<span>0.63
7. $7 *0.0625= $ </span>0.4375
8. $9 *0.7= $6.30
Answer: They ate at the same pace.
Step-by-step explanation: assuming you want to know who ate more faster you can do 18 / 30 and 24 / 4 to find out who ate more in 10 seconds each.
18 / 3 = 6 and 24 / 4 = 6. So they ate at the same speed / pace.
Hope this helps! Brainliest and / or a rating out of 5 stars would be appreciated :)
