Logan made a profit of 210 as a mobile groomer. he charged 75 per appointment and received 35 in tips but also had to pay a rental fee for the truck at 10 per appointment write an equation to represent this situation
explain how the equations from part pand part b differ

step-by-step explanation:

income: 75 * number of appointments + 35

costs: 10 * number of appointments

formula:

profit = income - costs = 75 * number of appointments + 35 - 10 * number of appointments

number of appointments * (75 - 10) + 35 =

65 * number of appointments + 35

41

Step-by-step explanation:

Lets say blue marbles are B and yellow marbles are Y .

We know Y is twice B plus one, so Y = 2*B + 1

We also know that there are 61 marbles in total and there are only blue and yellow marbles, so

Y + B = 61 .

But wait, disnt we say Y = 2*B+1 ? Then we can rewrite that to:

2*B + 1 + B = 61

If we remove 1 from both sides, we get:

2*B + B = 60

Since 2*B = B+B, we know that B+B+B would be 3*B

So now we have 3*B = 60.

We divide both sides by 3 and we get B = 20

And then we go way back to Y being twice B plus one.

If B is 20, twice B would be 40. Plus one, 41.

So Y = 41

P.S. I found this on the internet!
