I need help on this

Tasya [4]

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

So $19.25 is the tax amount.

To get the total price, you add:

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

$294.25 is the total amount that Anna has to pay.

To get what Anna has left over, you subtract:

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

Anna has $135.75 left.

I hope this helped you a lot!

Answer:

$\frac{log_{9}17 }{log_{9}10 }$

Step-by-step explanation:

Using the change of base rule for logarithms

$log_{b}$ x = $\frac{log_{c}x }{log_{c}b }$ ( where c is the new base )

Given

log 17 , that is $log_{10}$ 17 , then

$log_{10}$ 17 = $\frac{log_{9}17 }{log_{9}10 }$
