Let x be the cost of a sandwich

7 = 4x + 4 (x-0.75)
7 = 4x + 4x - 3
10 = 8x
8x = 10
x = 10/8
x = 1.25

Answer : The cost of sandwich is, $1.25

Step-by-step explanation :

Let the cost of sandwich be 'x' and the cost of container of milk be, 'y'

A sandwich costs $0.75 more than a container of milk. The equation will be:

x=0.75+y       .............(1)

A customer buys 4 sandwiches and 4 containers of milk. The customer pays $7.00. The equation will be:

4x+4y=7.00     ..............(2)

Now substitute the value of 'x' from equation 1 to equation 2, we get the value  of 'y'.

4x+4y=7.00

4(0.75+y)+4y=7.00

3+4y+4y=7.00

3+8y=7.00

8y=7.00-3

8y=4.00

y=\frac{4.00}{8}

y=0.5

Now put the value of 'y' in equation 1, we get the value of 'x'.

x=0.75+y

x=0.75+0.5

x=1.25

The cost of sandwich = x = $1.25

The cost of container of milk = y = $0.5

Thus, the cost of sandwich is, $1.25

A rectangular auditorium seats 1564 people. the number of seats in each row exceeds the number of rows by 1212. find the number
yanalaym [24]
<span>We can safely assume that 1212 is a misprint and the number of seats in a row exceeds the number of rows by 12. Let r = # of rows and s = # of seats in a row. Then, the total # of seats is T = r x s = r x ( r + 12), since s is 12 more than the # of rows. Then r x (r + 12) = 1564 or r**2 + 12*r - 1564 = 0, which is a quadratic equation. The general solution of a quadratic equation is: x = (-b +or- square-root( b**2 - 4ac))/2a In our case, a = 1, b = +12 and c = -1564, so x = (-12 +or- square-root( 12*12 - 4*1*(-1564) ) ) / 2*1 = (-12 +or- square-root( 144 + 6256 ) ) / 2 = (-12 +or- square-root( 6400 ) ) / 2 = (-12 +or- 80) / 2 = 34 or - 46 We ignore -46 since negative rows are not possible, and have: rows = 34 and seats per row = 34 + 12 = 46 as a check 34 x 46 = 1564 = total seats</span>
