Abook store surveyed 100 customers about their favorite type of book. if 32 costumers preferred science fiction how many customers out of 1500 could be expected to prefer science fiction

480

Step-by-step explanation:

This is a problem you can solve by using proportions.  If 32 out of 100 prefer sci-fi, then the ratio representing that looks like this:

Since you have the sci-fi "stuff" on top and the "total number of customers" on the bottom, the next ratio you set up with your unknown needs to follow the same set up.  You are asked how many customers (x) out of 1500 (total number of customers) would prefer sci-fi?  That ratio would look like this in the proportion:

×

Cross multiply to get 100x = 48,000

Solve for x by dividing both sides by 100:

x = 480

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
