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). rachel’s 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

Please mark brainliest!

Part 1:

Plan 1: y = 25x

Plan 2: y = 120 + 10x

x = number of weeks

y = total money

Part 2:

Plan 1 requires 8.8 weeks.

220/25 = 8.8

Plan 2 requires 10 weeks.

220 - 100 = 100

100/10 = 10 weeks

Plan 1 is best since the money is earned faster.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
