suter [353]
Lets try to solve this problem using 2 equations, also,we will have bananas=b and pears =p

5b+3p= $3.80
2b+4p= $3.20  i will divide this equation by 2 and get
b+2p= $ 1.60  we subtract 2p from both side so i can find the cost for 1 banana
b+2p-2p=1.60-2p
b= $1.60-2p

I will replace the b in the first equation now,

5(1.60-2p)+3p=$3.80
8-10p+3p=3.80   solving for p
8-7p=3.80     we subtract 8 from both sides
-7p=-8+3.80
-7p=-4.20  we multiply both sides by (-1)
7p=4.20  we divide now both sides by 7
p=0.60   a pear cost 0.60 cents

a banana is b=1.60-2p,   b=0.40 cents

My son, Garrett, is 11 years old and has a piggy bank that he wants to fill. He started with 5 one dollar bills. Every Saturday
Debora [2.8K]

Answer:

1) M(x) = 5 + 3x

2) Dependent variable; 3 dollar bills

Independent variable: chores

3) Range is continuous

Domain is discrete

4) Range: 0 ≤ x ≤ 10

Domain: 5 ≤ M ≤ 35

Step-by-step explanation:

We are told he started with 5 number of $1 dollar bills and that every Saturday, he earns 3 more $1 dollar bill.

Thus, total number of $1 bills earned after x number of Saturdays(weekly) is;

M(x) = 5 + 3x

After 10 weeks, total number is;

M(10) = 5 + 3(10)

M(10) = 35

The dependent variable is the 3 more dollar bills earned each Saturday because it depends on chores he completed. While the independent variable is the chores because it doesn't depend on anything.

After 10 weeks, the range and domain will be;

Range: 0 ≤ x ≤ 10

For the; Domain:

For x = 1, M(0) = 5 + 3(0) = 5

M(10) = 35

Thus;

Domain: 5 ≤ M ≤ 35

The range could be all numbers in the interval from 0 to 10. Thus, it is continuous.

Whereas, the domain doesn't contain all the numbers in the interval from 5 to 35. Thus it is Discrete.
