Can someone help? please

Andrea went to the store to buy sweater that was on sale for 40% off the original price it was then put on clearance an additional 25% off the sale price she also use a coupon that saved her an additional five dollars and j did not spend more than $7.60 for the sweater what are the possible values for the original price of the sweater?

Factorize: x^2+8x+10 i just solved it but i don't know if the process is correct

If f(x) = 2x + 2 and g(x) = x? , what is (gºf)(2)?
