Question

The graph shows the price, in dollars, of different numbers of sweet breads at Alan's store. The table shows the price, in dollars, of different numbers of shortcakes at the same store. A graph shows Number of Sweet Breads on x-axis and Price of Sweet Breads on y-axis. The x-axis scale is shown from 0 to 30 at increments of 5 and the y-axis scale is shown from 0 to 160 at increments of 20. A straight line joins the ordered pairs 5, 20 and 10, 40 and 15, 60 and 20, 80 and 25, 100 and 30, 120. Shortcake Number of Shortcake Price of Shortcake (dollars) 5 45 10 90 15 135 20 180 How many dollars more is the price of a shortcake than the price of a sweet bread at David's store?
$4 $5 $9 $25

Answer 1

Answer:

$5 is the answer.

Step-by-step explanation:

when you plot out the graph for line #1 and take the highest coordinate and divide the biggest number by that smallest number using rise over run (or any coordinate for the line it is a constant proportion) you find that the constant proportionality is $4 (which is a reasonable price for a shortcake) doing the same to line #2 you find that the price for  a single cupcake is $9.

All you have to do to fine the difference between them is to subtract the higher number from the smaller one. $9 - $4 = $5

There's your answer!!!! Brainliest plz!!!
