Eli and Samantha work at a dry cleaners ironing shirts. Eli can iron 20 shirts per hour, and Samantha can iron 35 shirts per hou
Tomtit [17]

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

20x+35y=400 -----> equation A

Samantha worked 2 more hours than Eli

so

y=x+2 ----> equation B

solve the system by substitution

substitute equation B in equation A

20x+35(x+2)=400

solve for x

20x+35x+70=400\\55x=330\\x=6

Find the value of y

substitute the value of x in equation B

y=6+2=8

therefore

The number of hours Eli worked was 6 and the number of hours Samantha worked was 8

Someone please help and thx
gogolik [260]

Answer:

  60 + 70n ≤ 200

Step-by-step explanation:

Since the $200 is a maximum, only inequalities with "≤ 200" make any sense in this context.

Since the unit rate for training sessins is $70, only expressions containing 70n make any sense in this context.

The only inequaity that makes any sense in this context is ...

  60 + 70n ≤ 200

Using the given data you can build the linear regression (described by linear function y=ax+b) by hand or you can use math calculator to do this. In attached diagram you can see that

a=-26.059\approx -26

and

b=722.633\approx 723.

Then the equation of linear function is

y = -26x + 723.

Answer: correct choice is D.
