4b+2c=36, solve for b, subtract 2c from both sides
4b=36-2c divide both sides by 4
b=9-0.5c
Then we are told that:
7b+3c=59, using b=9-0.5c we get:
7(9-0.5c)+3c=59 perform indicated multiplication on left side
63-3.5c+3c=59 combine like terms on left side
63-0.5c=59 subtract 63 from both sides
-0.5c=-4 divide both sides by 0.5
c=8
So each souvenir cup costs $8.
(and each bag of cotton candy is $5)
To determine The probability of both of these occurring, you would multiply the probability of each together. So, there is a 1/7 chance of the first salesman getting the right key, and 1/6 chance of the second salesman getting the right key. 1/7 x 1/6= 1/42 chance of both occurring.
1g = 1,000mg
0.5g = 0.5 · 1,000mg = 500mg
