Chen has an unlimited supply of square tiles. she has 1 cm x 1 cm tiles, 2 cm x 2 cm tiles, 3 cm x 3 cm tiles, and so on. every tile has integer side lengths. a rectangular table top with an 84 cm x 112 cm surface is to be completely covered by identical square tiles, none of which can be cut. chen wants to use the minimum number of identical tiles to complete the job in order to reduce her costs. determine the minimum number of identical tiles required to completely cover the table top.

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

126 maybe. sorry
