6 0

Answer:

-169

Step-by-step explanation:

We want to isolate v.

Method 1:  subtract 40 from both sides, obtaining  169 = -v.  Then change the sign of both sides, arriving at v = -169.

Method 2:  Add v to both sides.  Then v + 209 = 40.

Now subtract 209 from both sides, obtaining -169.

Mary wants to buy one large pizza, one medium pizza, and three drinks. The drinks cost $p$ dollars each, the medium pizza costs
Korolek [52]

Answer:

30-8p

Step-by-step explanation:

Let p represent cost of each drink.

We have been given that the medium pizza costs two times as much as one drink, so the cost of medium pizza would be 2p.

We are also told that the large pizza costs three times as much as one drink,  so the cost of la pizza would be 3p.

We have been given that Mary wants to buy one large pizza, one medium pizza, and three drinks.

Since the cost of one drink is p, so cost of 3 three drinks would be 3p.

The total cost of one large pizza, one medium pizza, and three drinks would be 2p+3p+3p=8p

Mary started with $30, so amount left after all of her purchases would be 30 minus total cost of all purchases.

30-8p

Therefore, Mary will have 30-8p dollars left after making all of her purchases.

remember that percent is parts out of 100 so x%=x/100
basically just remove the percent sign and move the decimal place 2 places to the left  to convert to fraction

the first one
20 dollars
4.75% tax
15% tip
it depends if you want to tip on the total with tax or without tax
it is better to top on the without-tax value since tax comes from you so
find 4.75% of 20 and add that to 15% of 20 then add that to 20 to get the proper value

scenarios
1. 20+(20 times 4.75%)+(20 times 15%)=23.95
2. ([(20 times 104.75%)] times 115%)=24.09
both are bellow $25 so $25 shoudl be enough to cover it




total cost of a spa treatment of 42 with 6% tax and 20% tip
so you could again do two things:
1. apply tax and give tip on the new amount
2. find the tip and add that to the tax of only 42

scenarios:
1.(42 times 106%) times 120%=$50.4
2. (42 times 20%) +(42 times 106%)=$52.92
it depens on what you tip on
