Adams arcade charges an entrance fee of $7.50 and 0.45 per game. Jims jamming does not charge an entrance fee but the games are

STALIN [3.7K]

Answer:

Step-by-step explanation:

cost of playing x games at Adams = 7.50 + 0.45x

cost of playing x games at Jims = 1.25x

1.25x = 7.50 + 0.45x

1.25-0.45x = 7.50

0.80x = 7.50

x = 7.50/0.80 = 9.375 , but x must be an integer.

The cost is never the same. When x ≤ 9, Adams costs more. When x ≥ 10, Jims costs more.

Jill sold half of her comic books and then bought sixteen more. She now has 36. With how many did she begin?

Alex777 [14]

Answer:

$\frac{1}{2}x + 16 = 36$

40 comic books

Step-by-step explanation:

Let x be the Jill comic books.

Given:

Jill sold half of her comic books and then bought sixteen more. She now has 36.

$\frac{1}{2}\ (Jill\ books) + 16\ more\ books = 36$

$\frac{1}{2}\ (x) + 16 = 36$

$\frac{1}{2}x + 16 = 36$

Therefore the algebraic equation of the given statement.

$\frac{1}{2}x + 16 = 36$ --------(1)

Now we solve above equation for x.

Subtract by 16 both side of the equation 1.

$\frac{1}{2}x + 16 -16 = 36 -16$

$\frac{1}{2}x = 20$

Multiply by 2 both side of the above equation.

$2\times \frac{1}{2}x =2\times 20$

$x = 40$

Therefore, Jill had 40 comic books.
