Janet and her brother John went out to eat. Both paid the same amount. Janet got three burgers and left a $10 tip. John bought 4

lianna [129]

Answer:

Cost for 1 burger = 5 $

Amount spent by Janet = 25$

Amount spent by John = 25$

Explanation:

Let the cost for burger be p.

Janet got three burgers and left a $10 tip

Amount spent by Janet = 3 p + 10

John bought 4 burgers, but only left a $5 tip

Amount spent by John = 4 p + 5

Both paid the same amount.

So, we have 3 p + 10 = 4 p + 5

=> p = 5 $

So, cost for 1 burger = 5 $

Amount spent by Janet = 3 x 5 + 10 = 25$

Amount spent by John = 4 x 5 + 5 = 25$

Which best describes the meaning of the statement if A then B

Oliga [24]

Answer:

$a => b \equiv ( \neg a \ \lor \ b )$

Step-by-step explanation:

You can understand the statement from many perspectives, but in terms of proposition logic it is best to understand it as "negation of a" or " b" in mathematical terms is written like this

$a => b \equiv ( \neg a \ \lor \ b )$

You can show that they are logically equivalent because they have the same truth table.

Elis [28]

To get the answer we can use proportion
220 ----------------95.3%
x -------------------100%
Crossmultiply now
220*100%=95.3%*x
22000=95.3x /:95.3
22000:95.3=x
