Salvatore purchased several magazines for $2 each and books for $3 each. If he spent $160 on a total of 60 books and magazines altogether, what would be the number magazines that Salvatore purchased?

the number of magazines purchased is 20

Step-by-step explanation:

As it is mentioned in the question that there is a total of 60 books + magazine altogether

Here we used the following equations

Let us assume the number of magazines be x

ANd, the number of books be y

x + y = 60 (1)

2x+ 3y = $160 (2)

Now multiply with 2 in the equation 2

Then it comes

2x + 2y = 120

2x + 3y = 160

Solve these equations

y = 40

Now the x value is

x + 40 = 60

x = 20

Hence, the number of magazines purchased is 20

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
