Answer:

the sale price is 52.50

Step-by-step explanation:

30% discount means that the person pays 70% of the original price

multiply 75 by 70% written as a decimal 0.70

75*0.70 = 52.50

Answer:
The 30% discount is $22.50 off the original price. Thus, a 30% discount on $75 brings the total to $52.50.

Explanation:
First, calculate the 30% discount.

75 • .30 = 22.5

So, this means the 30% discount gives us $22.50 off the original price.

Next, subtract the discount from the original price to find the final total.

75 - 22.5 = 52.5

So, the final total is $52.50.

three adults and four children must pay $122 for tickets. Two adults and three children must pay $87. what are the price of each
Natasha2012 [34]

Let a be the price of an adult ticket, and c the price of a child ticket.

The sentence "Three adults and four children must pay $122 for tickets" translates to 3a+4c = 122

The sentence "Two adults and three children must pay $87" translates to 2a+3c = 87

Which leads to the linear system

\begin{cases} 3a+4c = 122\\2a+3c = 87 \end{cases}

You can solve this system as you prefer, for example you can multiply the first equation by 2 and the second by 3 to get

\begin{cases} 6a+8c = 244\\6a+9c = 261\end{cases}

Now subtract the first from the second:

(6a+9c) - (6a+8c) = 261-244 \iff c = 17

Now plug this value for c in any of the equations, for example the first:

3a+4c = 122 \iff 3a+4\cdot 17 = 122 \iff 3a+ 68=122 \iff 3a = 54 \iff a = 18

20 cartons of ice cream = 1 carton of ice cream = $4, meaning that $4 x 20 = $80

2 cartons of yogurt = 1 carton of yogurt = $1, meaning that $1 x 2 = $2

$80 + $2 = $82

Hope this helped!

Raul and his friends each way 1/20 of a ton are standing on a truck scale . The total weight shown by the scale is 3/4 of a ton
V125BC [204]

Answer: There are 15 friends.

Step-by-step explanation:

We know that there is N friends (N is the number that we are looking for)

Each friend weights 1/20 ton.

Now, the weight of the N friends together is N times 1/20 ton.

Then we have:

N*(1/20) ton = 3/4 ton

We solve this for N.

First multiply both sides by 20.

20*N*(1/20) = N = 20*(3/4) = 60/4 = 15
