Step-by-step explanation:
Let
x ----> the number of hours Eli worked
y ----> the number of hours Samantha worked
we know that
Eli and they ironed 400 shirts between them
so
----> equation A
Samantha worked 2 more hours than Eli
so
----> equation B
solve the system by substitution
substitute equation B in equation A
solve for x
Find the value of y
substitute the value of x in equation B
therefore
The number of hours Eli worked was 6 and the number of hours Samantha worked was 8

Answer:
maybe if u translate it in English
Step-by-step explanation:
it wouldv been helpful if u mind?
There are at least a few ways to do it, one of them being:
$8 - $5 = $3, so we may want to find out how much percent of 5 is 3.
3 = x% of 5
3 = x/100 * 5
3 = x/20 * 1
3 = x/20 / * 20 (both sides)
x = 60 [percent]
So now we know that 3 is 60% of 5. It also means that the increase from $5 to $8 was by <u>60%</u><u />.
