Can you answer question 45 and 46?<br> (Show work)
muminat

45. These word problems often seem to be two equations in two unknowns, here <em>h</em> for hits and <em>m</em> for misses.

"After 30 tries" translates into

h + m = 30

+5 for a hit, -10 for a miss, John lost 90 translates to

5h + -10 m = -90

We have

m = 30 - h

5h - 10(30 -h) = -90

5h - 300 + 10h = -90

15h = 210

h = 210/15 = 14

Answer: 14

Check: 5(14)-10(16)=-90, good

46. We have to make the odd assumption the grocer sells for his cost, but let's not beat up the question too hard.

Again, two unknowns, <em>b</em> kilograms of Brazil nuts and <em>c</em> kilograms of cashews.

<em>... sold 12 kg of the mixture ...</em>

b + c = 12

<em>... cashews $8/kg and Brazil nuts $10/kg and the results is $8.50/kg ...</em>

This one's a bit more involved to translate because we have to recognize the total price is the 8.50 per kg times 12 kg.

8c + 10b = 12(8.50) = 102.00

The solving is pretty much just like the last one; we eliminate the unknown we're not asked for.

b = 12 - c

8c + 10(12 - c) = 102

-2c = 102 - 120 = -18

c = 9

Answer: 9

Check: (9(8)+10(3))/12=102/12 = 8.50 good
