Answer:
x3+7x-3
Step-by-step explanation:
Sorry, I guess I was in a hurry. This is how I did it after carefully reading the problem.
9.54% times which mobile phone (the one we are looking for=y) would use 1.908
that is: 0.0954 times y=1.908
0.0954y=1.908 dividing each side by 0.0954, we get y=20
So, the answer is y=20, or the mobile phone is 20
Answer:
6.44
Step-by-step explanation:
subtract 6.50 by 4 which will give you 6.44
15t + <35> j (price * count sold)
Cost = <4.5>t + 5 j + 150
Profilt = Revenue - Cost = (15t + <35>j) - (<4.5>t + 5j + 150)
= 15t + <35>j - <4.5>t < - >5j - 150
= 50t - -9.5j - 150
