the markup rate is 144% .
clara schumann is buying bagels for her coworkers, she buys a dozen bagels priced at $5.49 a dozen.
selling price of a dozen bagels is $5.49 .
the bakery's cost for making the bagels is $2.25 per dozen.
cost price of a dozen bagels is $2.25 .
putting all the values in the formula
markup percentage = 144 %
therefore the markup percentage is 144% .
y = 8x
the slope is 8 and the y intercept is 0
that means our line will cross through the origin.
to graph start at the origin and move up 8 and right one or down 8 and left one. with either of these two points you should be able to complete your graph.
see the attachment.
option (1) is correct.
consider the given equation, 3y -5x ≥ -6
we have to choose the graph from the given option,
we first find the coordinate where the given equation touches x and y axis.
first consider for x axis,
we know at x-axis y coordinate is zero.
substitute y = 0 in the given equation , we have,
3y -5x ≥ -6 ⇒ 3(0) -5x ≥ -6 ⇒ -5x ≥ -6 ⇒ 5x ≤ 6 ⇒ x ≤ 1.2
(x,0) = (1.2, 0)
now, consider for y axis,
we know at y-axis x coordinate is zero.
substitute x = 0 in the given equation , we have,
3y -5x ≥ -6 ⇒ 3y -5(0) ≥ -6 ⇒ 3y ≥ -6 ⇒ y ≥ -2
(0,y) = (0, -2)
now plot according to given coordinate we get the below graph,
thus, option (1) is correct.
