Step-by-step explanation:

B) rose bush: $6, geranium $7

Step-by-step explanation:

Jose spent $70 on 7 rose bushes and 4 geraniums.

( 7 x $6 = $42 ) ( 4 x $7 =  $28 )

$42+$28= $70

Eugene spent $50 on 6 rose bushes and 2 geraniums.

( 6 x $6 = $36 ) ( 2 x $7 = $14 )

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
