Step-by-step explanation:
Does not compute *SPUTTER SPUTTER CRASH!*
Answer:
its 51
Step-by-step explanation:
First, let's use the Distributive Property to make our equation easier to solve. Remember that the Distributive Property says the following:

Using this, we can multiply the 7 out to the
and 3. This gives us:

Now, let's solve for
:



We can see that there is one solution for this equation because
is equal to one definite value after solving. Thus, our answer is A, one solution.
<h3>Jason bought 20 stamps of $0.41 each and 8 postcards of $0.26 each.</h3>
<em><u>Solution:</u></em>
Let stamps be s and postcards be p
Given that,
The number of stamps was 4 more than twice the number of postcards
s = 4 + 2p -------- eqn 1
Jason bought both 41-cent stamps and 26-cent postcards and spent $10.28
41 cent = $ 0.41
26 cent = $ 0.26
Therefore,

0.41s + 0.26p = 10.28 --------- eqn 2
Substitute eqn 1 in eqn 2
0.41(4 + 2p) + 0.26p = 10.28
1.64 + 0.82p + 0.26p = 10.28
1.08p = 10.28 - 1.64
1.08p = 8.64
Divide both sides by 1.08
p = 8
Substitute p = 8 in eqn 1
s = 4 + 2(8)
s = 4 + 16
s = 20
Thus Jason bought 20 stamps and 8 post cards
