Answer:

TOTAL TAX IS: $19.25

TOTAL PRICE IS: $294.25

MONEY LEFT IS: $135.75

Step-by-step explanation:

First, you do a proportion:

?/275 = 7/100

the ?/275 represents how much money in $275

the 7/100 represents 7% (7 hundredths)

then you cross multiply:

275 x 7 = 1925

then you divide:

1925 divided by 100 = 19.25

<em><u>So $19.25 is the tax amount.</u></em>

<em><u></u></em>

To get the total price, you add:

Tax ($19.25) + Cost($275) = $294.25

<u><em>$294.25 is the total amount that Anna has to pay.</em></u>

<u><em></em></u>

To get what Anna has left over, you subtract:

Has($430) - Spend($294.25) = $135.75

<u><em>Anna has $135.75 left.</em></u>

<u><em></em></u>

I hope this helped you a lot!

Answer: 150 boys

Step-by-step explanation:

Let the number of boys be x

Since there were 200 more girls than boys, the number of girls will be: = x + 200

Since the ratio of boys to girls was 3:7, this can be solved further below:

3/7 = x/x+200

Cross multiply

(7 × x) = 3(x + 200)

7x = 3x + 600

7x - 3x = 600

4x = 600

x = 600/4

x = 150

The number of boys enrolled is 150

Number of Girls will be:

= X + 200

= 150 + 200

= 350

Check: Number of boys / Number of girls

= 150/350

= 3/7

= 3:7

Dovator [93]

Answer:

D. no solution

Step-by-step explanation:

h-z=3(1)

h=3+z(minus z from both side)

put in the second equation

-3h,+3z=6(2)

-3(3+z)+3z=6

-9-3z+3z=6

-9=6( not true)

so the equation doesn't have a solution.
