Ron and kathy are ticket sellers at their class play, ron handling students tickets that sell for $2.00 each and kathy selling adult tickets for $4.50 each. if their total income for 364 tickets was $1175.50, how many did ron sell?

Let's create two equations and solve them using the substitution method.

Solve the first equation for s.

Plug s into the second equation.

Plug 179 for a into the first equation.

Since Ron handled student tickets, he sold 185 tickets (s = student tickets = 185).

Let's check our work.

In the first equation, s + a = 364; let's plug in what we got for a and s into the equation.

This means we will plug in 179 for a and 185 for s.

185 + 179 = 364

189 + 179 does equal 364, so this means we are correct in solving this system of equations.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
