Let assume x be the sale price
A clothing store advertises that it is having a 25% off sale.
The sale price with 25% discount is f(x) = sale price - 25% of sale price
f(x)= x - 0.25x = 0.75x
For one day only, the store advertises and additional savings of 10%.
The sale price with 10% discount is g(x) = sale price - 10% of sale price
g(x)= x - 0.10x = 0.90x
Use composition function
g(f(x)) = g( 0.75x) = 0.90(0.75x) = 0.675x
That is 0.675/100 = 67.5%
The total percent discount = 100% - 67.5% = 32.5%
what would be the sale price of a $40 sweater?
Here sale price x= 40
So we plug in 40 for x
g(f(40)) = g( 0.75(40)) = 0.90(0.75(40)) = 0.675(40) = 27
The sale price of sweater = $27
Answer: Cara takes longer to get to the library. She used 3 minutes more
Step-by-step explanation:
Cara leaves her house at 10:03 and arrives at the library at 10:17. The number of minutes used by Cara will be:
= 10.17 - 10.03
= 14 minutes
Irena leaves her house at 11:55 and arrives at the library at 12:06. The number of minutes used by Irena will be:
= 12.06 - 11.55
= 11 minutes
Cara takes longer to get to the library. She used (14 - 11) = 3 minutes more
Answer:
9
Step-by-step explanation:
In order to round to the nearest ten you must think: what is the nearest multiple of 10. For example, to round 68 to the nearest 10, the nearest whole number is 70, so the answer would be 70. However if you were to round 63 to the nearest 10, to would be 50 since that is the nearest multiple of 10

A logarithm of a number is the exponent to which the base of the logarithm must be taken to equal the number.
Example the logarithm (log) to the BASE 10 of 100 is 2 because
10^2 = 100
The log to base 10 of 1000 = 3 as 1000 = 10^3
The log to the base 3 of 9 is 2 because 9 = 3^2
- or we can say 2 is the log to base 3 of 9.
