sanita is buying 5 posters that are all the same price. the store has a sale that takes $3 off the regular price of each poster. she pays a total of $63. she wants to know the regular price of one poster

$15.60

Step-by-step explanation:

So, if Santia buys all five posters and pays $63 then we have to first find the value of 1 poster that is on sale so:

63 ÷ 5 = 12.6.

Now that we know how much 1 poster on sale costs we need to add the back that which was was taken off due to the sale:

12.6 + 3 = 15.6

So 1 poster at original price is $15.60

$15.6

Step-by-step explanation:

Sanita pays $63 for 5 posters that are $3 off each, if you divide 63 by 5 you will get $12.6, so you have to add $3 to $12.6 to get 15.6 which was the original price of one poster.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
