Awarehouse store sells 5.5-ounce cans of tuna in packages of 6. a package of 6 cans costs $9.24. the store also sells 6.5-ounce cams of the same tuna in packages of 3 cans for $4.68. it also sells 3.5-ounce cans in packages of 4 cans for $4.48. which package has the lowest cost per ounce of tuna?

Second package costs the lowest.

Step-by-step explanation:

A ware house sells tuna cans weighing = 5.5 ounce

It sells the cans of tuna in the package of 6.

Weight of 6 cans = 5.5×6 ounce

Cost of the 6 cans = $9.24

Therefore, cost of 1 tuna can = per oz

Now weight of second type of tuna can = 6.5 ounce

Weight of 3 cans = 3×6.5 = 19.5 ounce

Cost of 3 tuna cans = $4.68

Cost of 1 tuna can =

                              = $0.24 per oz.

Similarly cost of third type of tuna can =

                                                                = $0.32 per oz

Second package has the lowest cost per ounce of tuna.

step-by-step explanation:

d

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
