First make and equation. Since you want to find the number of the day where both charge the same total amount, you would make the equation:
let x= the number of days
110+46(x)=70+54(x)
Solve:
110-70+46(x)=70-70+54(x)
40+46(x)=54(x)
40+46(x)-46(x)=54(x)-46(x)
40=8(x)
40/8=8x/8
5=x
Therefore your answer would be 5 days

Answer:
210=75x-10x+35
Step-by-step explanation:
So we know to total profit he made is 210 dollars, in which he earned from 3 independent reasons.
The profits he made in per appointment will need a variable because we don't know how many appointments he made. So knowing that we can conclude that 75 dollars and 10 dollars per appointment has to have a variable after it. The same variable as well because both of which are money.
As of the tip, we don't need a variable because it is a one time addtion, he recieved a total of 35 dollars after all of the appointments, so no need to know how many. We already know the total.
So that leaves us to write an equation. The total=$per appointment-fee per appointment+tip. Which becomes 210=75x-10x+35.
Hope this helps!
Answer:
x < 5
Step-by-step explanation:
Step 1: Simplify
7x−35<2x−10
Step 2: Substract 2x from both sides
7x−35−2x<2x−10−2x
5x−35<−10
Step 3: Add 35 to both sides
5x−35+35<−10+35
5x<25
Step 4: Divide by 5
5x/5 × 25/5
x < 5
