Sam has 30.00 in his checking account and earns 8.00 per week as a allowance how many weeks will it take Sam to earn 78.00

6 weeks

Step-by-step explanation:

end goal = $76

how much he has in the bank = $30

how much he earnes per week = $8

first, subtract 30 from 78 to figure out how much he has left to ear:

$78 - $30 = $48

then take the difference and divide it by 8 since he earned $8 per week:

48 ÷ 8 = 6

It will take him 6 remaining weeks to complete his end goal.

the distance between point a and point b is 6 units
