The following are prices from a collection of hot dog vendors. Joe sells his hot dogs for
$1.50 each; Mike sells 2 hot dogs for $2; Jen sells hot dogs for $1.25 each; and Sue sells
3 hot dogs for $2.25. Who has the best deal? (CCSS6.RP. A.3)

A:Joe

B:Mike

c:Jen

D:Sue

Step-by-step explanation:

To solve this, you need to find the unit price by dividing the cost by the amount. For Mike, divide $2 by 2 to get 1. So, Mike sells hot dogs for $1. Next, divide 2.25 by 3 to get $0.75. So, Sue sells hot dogs for $0.75.

Joe: $1.50

Mike: $1

Jen: $1.25

Sue: $0.75

So, the best deal is Sue because it is the cheapest per unit. Hope this helped!

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
