Y= 80.55% approximately, 80.6% rounded up

Calculations:

The percent (percentage) of a given number p/q can be found, for the most part, without a calculator by a slight change in the notation:

y=the number 29/36 expressed as a percent becomes

y=[29(2.7777777778 approx.)]/[36(2.7777777778 approx.)]

y=0.8055 approx. (Express the decimal numeral as a percent)

y=0.8055(100)

y=

80.55% approx., which is 80.6% rounded up to the nearest tenth percent

Dorian buys 2 pounds of almonds for $21.98 and 3 pounds of dried apricots for $26.25. Which is less expensive per pound? How muc
ozzi

Answer:

The apricots are less expensive per pound.

Step-by-step explanation:

Cost of 1 pound of almonds = 21.98/2

Cost of 2 pounds of almonds = $21.98

So then you have to do 21.98 - 21.98/2. Which equals $10.99

Cost of 1 pound of dried apricots = 26.25/3

Cost of 3 pounds of dried apricots = $26.25

So then you have to do $26.25 - 26.25/3 which = $17.5 then divide that by 2 which equals $8.75.

To find out how much less expensive you have to find the difference, so to do that you have to do $10.99 - $8.75 = $2.24 per pound less expensive.
