X + y = 152, 8.5x + 12y = 1,656 How many hats were sold?

Elodia [21]

Answer:

x = 48 and y = 104

Step-by-step explanation:

Given equations are:

$x+y = 152\\8.5x+12y=1656$

From equation 1:

$x = 152-y$

Putting the value of y in equation 2

$8.5(152-y)+12y = 1656\\1292-8.5y+12y = 1656\\3.5y+1292 = 1656\\3.5y = 1656-1292\\3.5y = 364\\\frac{3.5y}{3.5} = \frac{364}{3.5}\\y = 104$

Now we have to put the value of y in one of the equation to find the value of x

Putting y = 104 in the first equation

$x+y = 152\\x+ 104 = 152\\x = 152-104\\x = 48$

Hence,

The solution of the system of equations is x = 48 and y = 104

The value of variable which was assumed for number of hats, is the total number of hats.

You are at a restaurant and your bill comes to $31.18. The sales tax is 6% and you give the waitress a 20 percent tip on the tot

Vanyuwa [196]

Answer:

$ 0.34 or 34 cents

Step-by-step explanation:

Bill amount = $31.18

sales tax = 6% of $31.18

= 0.06 ($31.18)

= $1.8708

Bill with tax = $31.18+$1.8708

= $33.0508

value of tip = 20% of 33.0508

= 6.61016

Total payment = 33.0508+ 6.61016

= $39.66096

or $39.66

We get change of $40 - $39.66

= $ 0.34

We shall get back in cents that will be 34 cents

Devante has a lunch account in the school cafeteria His starting balance at the beginning of the month is $35.50. The first wook

Alisiya [41]

Answer:

D the amount of money he pays for each lunch

Step-by-step explanation:

In each lunch Devante has, he pays 2,50 $ according to:

Money in t = t₀ he has 35,50 $ paid 3 lunches and spent

35,50 - 28 = 7,5

Then the cost of each lunch is 7,5 / 3 = 2,5 $

After that

bought 5 lunches and spent 28 - 15,5 = 12,50

Again 12,5 / 5 = 2,5 $

Now the model for the situation is a straight line with a slope 2,5

In an x , y cartesian system in which y is money in the account and x is the number of lunches, such a straight line will be

y = b - m*x ( b the intercept on y and m the negative slope)

y = 35,50 - 2,5*x

So answering the question is lyrics D the amount of money he pays for each lunch

-3b-(-2)=4b-12 show work please ASAP

makvit [3.9K]

Solve the equation:

– 3b – (– 2) = 4b – 12

– 3b + 2 = 4b – 12

– 3b = 4b – 12 – 2

– 3b = 4b – 14

– 3b – 4b = – 14

– 7b = – 14

– 14
b = ———
– 7

b = 2 <——— solution.

I hope this helps. =)
