Rachel really wants to purchase a new skateboard and her mother has agreed to give her a weekly allowance that she can save until she has $220 (enough to buy the skateboard). rochelle mother is a math teacher and presents two different plans for paying her weekly allowance

plan 1: a fixed weekly payment of $25

plan 2: a 120 initial plus payment $10 per week

part 1: write an equation for each plan explain what information the variables and numbers represents

part 2: which plan requires number of weeks to save enough money for the kateboard? explain or show your work

Step-by-step explanation:

10x+ 150=220 is the equation for the second plan you subtract 150 from 220 to get 70 and divide that by 10 and you get 7 which is the number of weeks it'll take

220/25=x

So for this one it'll take 8.8 weeks to get enough money and you divide 220 by the amount which is 25 to get 8.8 the number of weeks I'll take

I dont understand what the second one is asking so sorry dude but I think that's right

Yt

Step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
