C = # of children and charged $3.50 each

A = # of adults and charged $9.00 each

($3.5 x C)+ ($9.0 x A) = $1505

(this represents the total amount of money collected)

A + C = 210 (total number of people who got in)


So now you have two equations and two unknowns - so you can solve it via substitution.


A = 210 - C

Put this term for C into the other equation

3.5*C + 9*(210-C) = 1505

3.5C + 1,890 - 9C = 1505

385 = 5.5C

C = 385/5.5

C = 70 Children


A = 210 - 70

A = 140 Adults



Find the graph where the lines intersect at those two numbers

Bridget went fishing with her dad. Bridget Bridget caught the first fish of the day, another was 2 more than 3 times the weight
Arturiano [62]

Answer:

Bridget's first fish =f = 5 ounces

Bridget's dad first fish weighs 17 ounces

Step-by-step explanation:

Solution:

Bridget's fishes:

f ounces

2f ounces

3f+2 ounces

1/2f ounces

3/5f ounces

Total= f +2f + (3f+2) + 1/2f +3/5f

=3f + 3f + 2 + 5f+6f/10

=6f + 2 + 11f/10

=60f+11f/10 +2

=71/10f +2

Bridget's dad fishes

3f+2

4/5f

2f+4

1/2f

Total =(3f+2) + (2f+4) + 4/5f +1/2f

=3f+2+2f+4 + 8f+5f/10

=5f + 6 + 13/10f

= 50f+13f/10 + 6

=63/10f +6

Equate the total weight

71/10f +2=63/10f +6

Collect like terms

71/10f - 63/10f =6-2

71f-63f/10 = 4

8f/10=4

Cross product

8f=40

Divide both sides by 8

f=5

Bridget's first fish =f = 5 ounces

Bridget's dad first fish = 3f +2

=3(5)+2

=15+2

=17 ounces

Bridget's dad first fish weighs 17 ounces
