Jessica and her 2 sisters want to take a camping trip. They have $225 saved so far. Each of them will save $21 a week until they have $512 to pay for the trip. How much money will they save after 4 weeks?

225 + 63n for n- a natural number,

set 512=225+63n to find total number of weeks

63=21*3

use n=4 to solve the amount saved in 4 weeks

they wont 60*4=240, 240+12, 252+225=477

how much are the saving a day

what do they need to put up to have enough in 4 weeks

how much a day do the need to save to go in 1 week

etc

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5
