Maria is shopping for dog food. brand a is 40-pound bag and cost $49. brand b is 20-pound bag for $23.44

a) find the unit rate price (cost per pound for each brand)

b) which brand is cheaper per pound

brand a is $1.22 per pound.  brand b is $1.17 per pound.

Step-by-step explanation:

brand b would be the cheapest per pound but brand a would be better because brand b would be doubled price wise to get the same amount as brand a.

Brand B is cheaper than Brand A

Step-by-step explanation:

Brand A:

49/40=1.23

1.23*40=49

Brand B:

23.44/20=1.17

1.17*20=23.4

-232

step-by-step explanation:

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
