Edward’s recipe for salad uses a ratio of 3 3/4 cups of lettuce to 1/2 lb of tomatoes. use a complex fraction to compare the amount of lettuce to the amount of tomatoes. determine how many cups of lettuce edward needs to mix with 1 lb of tomatoes. show your work.

It would be 7 1/2. Here's a picture of how I did it

Step-by-step explanation:

I used a method called keep change flip to divide the 3 3/4 and 1/2. I got 30/4, then divided the improper fraction, and got 7 2/4. Then reduced it by 2 and got 7 1/2.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
