C(x) = 1200(40) + 100
or
= mx+c
where m = 1200, x = 40, y = 100
hope it helped,
click thx if it did.
Given:
Principal = 2,500
rate = 3.5%
term = 6 years
Simple interest = Pricipal x rate x term
S.I. = 2500 x 3.5% x 6
= 87.50 x 6
S.I. = 525.00 CHOICE C.
Suzanne will earn an interest of $87.50 per year and a total of $525 interest at the end of 6 years.
Answer:
The amounts of three parts of the investment are 18000, 6000, 5000 respectively.
Step-by-step explanation:
An investment of $29,000 was made by a business club.
Let the amount of first and second investment be x and y respectively. So, the amount of third investment is (29000-x-y).
The first part of the investment earned 8% interest, the second 6%, and the third 9%. Total interest from the investments was $ 2250.
On simplification we get
..... (1)
The interest from the first investment was 4 times the interest from the second.
.... (2)
From (1) and (2) we get
Divide both sides by 0.06.
Put this value in equation (2).
The amount of third investment is
Therefore the amounts of three parts of the investment are 18000, 6000, 5000 respectively.
Answer:
standard form to represent the situation equation is 5a + 4.75b = 72.50
Step-by-step explanation:
given data
selling popcorn = $5.00
hotdogs = $4.75
makes = $72.50
solution
we consider here number of bucket sold = a
and number of hotdogs sold = b
Then after 1 hour she makes $72.50
equation for number of popcorn and number of hotdogs sold after an 1 hour is express as
$72.50 = number of bucket sold × price of popcorn per bucket + number of hotdogs sold × price of hotdog ...............................1
put here value and we get
72.50 = 5 × a + (4.75) × b
5 a + 4.75 b = 72.50
so here equation is equivalent to the standard form in the linear equation that is express ( Ax + By = C )
and here A and B are non zero with A, B and C all three are real number
so standard form to represent the situation equation is 5a + 4.75b = 72.50
