You have to make a problem that could happen in the real world that multiplication of a fracton using product between 10 and 15
Answer:
y-8+3y+12
4y+4
Step-by-step explanation:
y-8+3y+12
4y+4 is your answer
I think it means like explain what are variable is. Only if your finding a variable: explain how you got the answer to that variable. Hope I helped!
This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=38+0.11X
Plan II: Y=49+0.07X
When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25
