Answer:
Hello! Good day to you!
Answer: $20.28
Step-by-step explanation:
Your answer here is quite simple here.
Alice bought 3/4ths of a kilogram of cheddar cheese. A SINGLE kilogram of cheddar cheese, according to your chart, costs exactly 2.16. When dealing with fractions, it's best to convert to a DECIMAL first.
Think of it as quarters (money). 1 quarter is 25c, 2 are 50c, 3 are 75c, 4 are $1.
Fractions are the same (on a simple level). 1/4= .25, 2/4=.50, 3/4=.75, 4/4=1.00.
So, 3/4 is like 3 quarters! Meaning 3/4 is .75
NOW we can get to solving this portion. When you have a fraction/decimal and you're attempting to discover portions of a specific item/object/anything, you MULTIPLY.
So, take your 3.28 and multiply it by .75. You get: 2.46 Alice bought $2.46 of cheddar cheese.
BUT YOU'RE NOT DONE!
She also bought 4 kilo's of American Cheese and 4.5 kilo's of ricotta!
Same method here applies.
4 kilo's of American cheese converts to 4.00. Multiply 4.00* 2.16, you get $8.64.
4.5 kilo's of ricotta * 2.04 = $9.18
YOU'RE STILL NOT DONE YET!
Now, add em all together!
$9.18+$2.46+8.64=$20.28
