Answer: Tom will pay $20.01 lesser than the original price.
Step-by-step explanation:
The original price of the phone is $137.99. It is now on sale for 1/10 off the original price. This means that the discount on the original price is 1/10 × 137.99 = 13.799. The new price will be the original price - the discount.
The new price is 137.99 - 13.799 = $124.191
Tom has a coupon for an extra 5% off the sale price. It means that Tom would pay 5% off $124.191. The amount that Tom would pay will be
124.191 - (5/100 × 124.191) = 124.191 - 6.20955 = $117.98
The difference between the original price and the price that Tom will pay is
137.99 - 117.98 = $20.01

Answer:
Option D
Step-by-step explanation:
We need the product of:
(-3s + 2t)*(4s - t)
We can use the distributive property:
(a + b)*(c + d) = a*c +b*c + a*d + b*d
Applying to our case:
(-3s + 2t)*(4s - t) = (-3s)*4s + (-3s)*(-t) + 2t*4s + (2t)*(-t)
(-3s + 2t)*(4s - t) = -12(s^2) + 3st + 8ts - 2(t^2)
(-3s + 2t)*(4s - t) = -12(s^2) + 11ts - 2(t^2)
So, the correct is option D negative 12 s squared + 11 s t minus 2 t squared
Answer:
175/48
Step-by-step explanation:
Convert 8 6/8 and 2 2/5 to fractions
8 6/8 = 70/8 ; 2 2/5 = 12/5
Now, we have : 70/8 : 12/5
= 70/8 x 5/12
= 70x5/8x12
=350/96
Simplify the fraction, we get 175/48
