the money given by joe to hector is 125$
let the hector works for x weeks,
it is given that hector earns 50$ in a week,
so the total money hector wants to save is 1100$
now

from the above inequality, we will find x

it means the hector will work for 20 weeks in order to earn 1100$.
So a negative and a negative is equal to a positive. The equation can be written as 48+14 which will give you 62.
'of' in math implies that the values are being multiplied together, so multiply 47 and 65%;
47 * 65% = 47 * .65 = 30.55
