Answer:
he earned $97.02 in one month
Step-by-step explanation:
Answer: p= $8 s= $2.50
Step-by-step explanation:
3p + 4s = 34 and 3p + 7s= 41.50
Since the number of pizzas DIDNT change between these two equations, we can use the total of the second equation to help us find the price of one sandwich.
41.50 - 34 = $7.5 for 3 sandwiches (7s-4s)
So how much is one sandwich? 7.50/3 = $2.50 for each sandwich
now that we know s, it’ll be much easier finding p. We can use one equation to find p.
3p + 4(2.5) = 34 (Solve algebraically)
3p + 10 = 34
- 10 | -10
3p = 24
3p/3 = 24/3
p = $8. Now you can check by substituting the variables!
I= PRT
I= 1400 X 0.015 X 0.5
I= 21 X 0.5
I= 10.5
if it was a full 12 months it would be
21 x 1= 21
if it was 1/5 years it would be
21 x 1.5 = 31.5 and so on
Sorry I can’t see the picture it’s blurry for me
That is a rhombus and the formula is A= PQ/2
