Larissa Caldwell · Answer 2

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
