Answer:
see the explanation
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:
1) 80 people 2) 15 weeks
Step-by-step explanation:
(x = the number of people)
500 + 8x = 1140 ← ($500 initially plus $8 per person equals $1140)
8x = 640 ←(subtract the $500 from each side)
x = 80 ←(divide by the $8 per person to get the number of people)
------
(x = the number of weeks)
242 = 62 + 12x ←(The cost of the snake ($242) is equal to her $62 plus $12 she saves every week)
180 = 12x ←(subtract the $62 from both sides)
15 = x ←(divide by the $12 per week)
