Kate bought 4 cans of soup for $2.67. How much would it cost for her to buy 10 cans?
gavmur [86]

Answer:

It would be 6.60

Step-by-step explanation:

first you have to find the price of one can, so you divided 2.67 by 4.

the answer would actually be 0.6675, but you have to stop at the tenths place for money, so in this case, it would be 0.66.

we multiply 0.66 by 10 and get 6.6 which is also 6.60

It would cost $6.60 to but 10 cans.

Idk if this helps, but I hope it does.

Alexandra [31]

Answer:

102.6666... feet in one second 1232 feet in twelve seconds.

Step-by-step explanation:

Most clear way of solving this breakdown the proportions by keep the value.

1 mile = 5280 feet.

1 hour = 60 minutes = 3600 seconds -- See now it is easy.

Feet per second...

                =  feet/seconds

(70*5280) = 369,600/3,600 = 102.666666667 -- That is 102.66...feet per second.

For twelve seconds just multiply by 12.

102.666666667*12 = 1232 feet in twelve seconds.
