The answer is $10
if you add up the total price for each of the items it totals to $40, she has $50 so $50-$40=$10
Answer: 120
Step-by-step explanation:
5!/(5-4)!=5!/1!=(5*4*3*2*1)/1
120/1
=120
For the first one your equation is h(d)=3/7d+5
If d represents the number of days and the question is wanting to know the height after 1 week (7 days) then you would get this equation once 7 is in the place of d
h(d)=3/7(7)+5
When solved you answer is 8 inch.
For the second one your equation is f(x)=75x+250
If x represents the number of weeks and the question is asking how much money Sam will have after 12 weeks then you will get this equation once putting in 12
f(x)=75(12)+250
Once solved you will get the answer $1150
Hope this helps! :)
