Answer:
16.5
Step-by-step explanation:
So lets find the change i savings for each week.
To do this, just subtract the value of the 1st week by the value of the 0th week:
7.50-6.50
=
1
So now we know for each week that passes, Henry's savings grows by 1 dollar.
Now, lets multiply the 1 dollar for each week by 10 weeks:
(dollar per week) x (amount of weeks)=(dollars for 10 total weeks)
1x10
=
10
Now that we know in 10 weeks Henry's savings increases by 10, lets add it to the orginal amount.
(Orginal amount) + (dollars for 10 total weeks) = (Total amount in savings)
6.50+10
=
16.5
Hope this helps! ;)
