Tim mowed lawns for 2 hours and earned $7.50 per hour. Then he washed windows for 4 hours and earned $6.30 per hour. What were Tim's average earnings per hour for all 6 hours? *

$40.20

Step-by-step explanation:

$7.50 per hour. Tim worked for 2 hours so you would do 2 timez 7.5 which is $15, the total he earned from mowing.

$6.30 per hour. Tim worked for 4 hours so you would do 4 times 6.3 which is $25.2, the total he earned from washing windows.

To get the total of how much he earned all together you add 15 and 25.2 and you get $40.2.

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
