If x is the number of hours Patricia needs to babysit, the inequality is

Therefore, since she has already saved $60,

Thus, the inequality that models the question is 60+5x>=200
Answer: see attached graph
<u>Step-by-step explanation:</u>
Choose values for t and plug them into the x equation and y equation to find the x,y coordinates.
Usually there is an interval provided. Since you did not specify an interval, I chose to use [-2, 2].

Ratio of Nickel to Zinc:
( 2/7 ) = ( Nickel /4.9)
Nickel = 1.4 lbs.
Ratio of Copper to Zinc:
( 9/7 ) = ( Copper /4.9)
Copper = 6.3 lbs.
Alloy = Zinc + Nickel +
Copper
Alloy = 4.9 lbs. + 1.4 lbs.
+ 6.3 lbs.
Alloy = 12.6 lbs.
