Each hotdog cost $1.50 and sodas cost $.50. At the end of the day you made a total of $78.50.You sold a total of 87 hot dogs and

Bond [772]

Answer:

The number of hot dogs sold was 35 and the number of sodas sold was 52

Step-by-step explanation:

Let

x ----> the number of hot dogs sold

y ----> the number of sodas sold

we know that

$x+y=87$

$x=87-y$ ----> equation A

$1.50x+0.50y=78.50$ ----> equation B

Solve the system by substitution

substitute equation A in equation B

$1.50(87-y)+0.50y=78.50$

solve for y

$130.50-1.50y+0.50y=78.50$

$1.50y-0.50y=130.50-78.50$

$y=52\ sodas$

<em>Find the value of x</em>

$x=87-52=35\ hot dogs$

therefore

The number of hot dogs sold was 35 and the number of sodas sold was 52

laila [671]

Mean = 450 sec
standard deviation = 50 sec
450-50 =400
450+50=500

Between 400 sec and 500 sec means one deviation above and one deviation below the mean, and it is 68%.

68%=0.68
0.68*288= 195.84≈196

Answer is d) 196
