Jasmine earned $150 last week. jay earned $130 last week. they combined their money and decided to donate 1/4 of their total amount to a charity. then ,they spent 40% of the remaining amount at an amusement park. jay claims that they only have 35% of their original combined total left .is jay's claim correct ?

last night Jasmine and Jay amount combined is $150+$130=$280

amount donated to charity is 1/4 of $280= $70

amount spent at an amusement park is` 40/100 x $210= $84

the remaining money = 280- (70+84)= $126

35% of their original amount is 35/100x$280=$98

so Jay's claim is not correct because the remaining money is $126 and not $98 as she Jay claims.

Explanation:

Hope this helps!

Have a great day! :)

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
