Question

which price below has the same unit rate as 3 cans for $ 1.98? Select All That Apply●6 cans for $4.00 ●5 cans for $5.90●2 cans for $1.32 ●4 cans for $3.60

Answer 1

Divide the price of 3 cans over 3 to find the unit rate:

`(1.98)/(3)=0.66`

Perform the same operation with the other rates to find which of them have the same unit rate:

6 cans for$4.00

`(4)/(6)=0.67`

5 cans for %5.90

`(5.90)/(5)=1.18`

2 cans for $1.32

`(1.32)/(2)=0.66`

4 cans for $3.60

`(3.60)/(4)=0.9`

Therefore, the only one which has the same rate as 3 cans for $1.98 is 2 cans for 1.32
