Kayla goes to math tutor who charges $30 a session in addition to a one time fee of $20. sara goes to a different math tutor who changes a one time fee of $10 and $35 per session. according to the graph, after a certain number of sessions the cost for each girl’s tutoring is about the same. what is that cost?

$80

Step-by-step explanation:

To solve this question you must first make an equation.

30 times however many sessions she has plus the $20 fee

Then $35 times however many sessions it is plus the $10 fee

you would then need to graph both to find where they meet.

$30(1)+20=50

$30(2)+20=80

$35(1)+10=45

$35(2)+10=80

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
