Im assuming by 5-.8, you mean 5/8ths and by 1-.4, you mean 1/4th...
x=5/8+1/4
x=5/8+2/8
x=7/8
They ate 7/8 together

Answer:
The answer is below
Step-by-step explanation:
1. COST Mr. Rivera wants to purchase a riding lawn mower, which is on sale for 15% off the marked price. The store charges sales tax 6.5% on all sales. Write a function p(x) that represents the price after a 15% discount. Write a function t(x) that represents the total cost with sales tax. Write a composition of functions that represents the total cost of a riding lawn mower on sale. How much will Mr. Rivera pay for a riding lawn mower that has a marked price of $3000?
Solution:
a) Let x represent the marked price and p(x) represent the price after discount. Since a discount of 15% is given, the price would be:
p(x) = ![x(100\% -15\%)=x(1-\frac{0.15}{100} )=0.85x](https://tex.z-dn.net/?f=x%28100%5C%25%20-15%5C%25%29%3Dx%281-%5Cfrac%7B0.15%7D%7B100%7D%20%29%3D0.85x)
b) If x = discounted price and t(x) = total cost with sales tax, then:
t(x) = ![x(100\% +6.5\%)=x(1+\frac{6.5}{100} )=1.065 x](https://tex.z-dn.net/?f=x%28100%5C%25%20%2B6.5%5C%25%29%3Dx%281%2B%5Cfrac%7B6.5%7D%7B100%7D%20%29%3D1.065%20x)
c) Let t(x) represents the total cost with sales tax
![t[p(x)] =p(x)+6.5\%\ of\ p(x) \\\\t[p(x)] = 0.85x+(0.065*0.85x)\\\\t[p(x)] =0.90525x\\\\for\ x=\$3000:\\\\t[p(3000)] = 0.90525*3000=\$2715.75](https://tex.z-dn.net/?f=t%5Bp%28x%29%5D%20%3Dp%28x%29%2B6.5%5C%25%5C%20of%5C%20p%28x%29%20%5C%5C%5C%5Ct%5Bp%28x%29%5D%20%3D%200.85x%2B%280.065%2A0.85x%29%5C%5C%5C%5Ct%5Bp%28x%29%5D%20%3D0.90525x%5C%5C%5C%5Cfor%5C%20x%3D%5C%243000%3A%5C%5C%5C%5Ct%5Bp%283000%29%5D%20%3D%200.90525%2A3000%3D%5C%242715.75)
Answer:
Yes
Step-by-step explanation:
There are infinite points between the two.
<u>Answer:</u>
![\bold{9+\frac{x}{5}=15}](https://tex.z-dn.net/?f=%5Cbold%7B9%2B%5Cfrac%7Bx%7D%7B5%7D%3D15%7D)
<u>Solution:</u>
Given: x=30
To solve: ![9+\frac{x}{5}](https://tex.z-dn.net/?f=9%2B%5Cfrac%7Bx%7D%7B5%7D)
On substituting the value of x,
![9+\frac{30}{5}](https://tex.z-dn.net/?f=9%2B%5Cfrac%7B30%7D%7B5%7D)
On dividing 30 and 5 we get,
![\Rightarrow 9+6 = 15](https://tex.z-dn.net/?f=%5CRightarrow%209%2B6%20%3D%2015)
So, the option is 15.
