Answer:
$7.34
Step-by-step explanation:
To compute sum of dollars that are not whole numbers. Using the sum of$5.89 and$1.45 as an illustration :
$5.89 + $1.45
Taking the whole numbers first:
$5 + $1 = $6
Take the sum of the decimals :
$0.89 + $0.45 = $1.34
Sum initial whole + whole of sum of decimal
$6 + $1 = $7
Remaining decimal : $1.34 - $1 = $0.34
$7 + $0.34 = $7.34
Put the values of the variables in place of the variables in the expression, then do the arithmetic.

It's A.
18 correlates with $350 and 12 correlates with $520.
That crosses off B and D.
18 + 12 days combined equals 30.
That excludes C and D.
A is your answer! :D
Find 10% of it (just move the decimal point one spot to the left) and multiply by 4
Answer:
The at least sign is ≥. So, h ≥ -12
