PLEASE HELP! ITS DUE AT 12! ITS 2 QUESTIONS! WILL MARK BRAINLIEST 1: Rick buys a remote control car to resell. He pays $28 in applies a mark up of 10%. what is his reselling price?

write an expression:
find the retail price:

2: A bicycle shop marks down each bicycle selling price by 30% for a holiday sell. what is the sale price of a bicycle that regularly cost $150?

write an expression:
find the sale price:

<3

1) The first expression is found by using the formula retail price = original cost + markup. If p is the original price, then the expression is p + 0.1p. The second expression can be found by simplifying the first expression. This gives 1.1p

b) Substituting p = 28 into the second expression gives 1.1(28) = 30.8 so the selling price is $30.80

Step-by-step explanation:

i don't know number 2 hope that helps

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
