Mathematics
1 answer:
diamong [38]4 years ago
8 0

Answer:

209 biology books and 125 psychology books were sold.

Step-by-step explanation:

x = biology books y = psychology books

334 = x + y

x = y + 84

x - y = 84

y = x - 84

Using these systems of equations, we can see that (209,125) is the only possible answer. Elimination, substitution, or guess and check are all viable methods to solve this problem. I can explain further if needed! :)

Each small box has 12 granola bars and each large box has 30 granola bars. The camp bought 2 more large boxes than small boxes,
sweet-ann [11.9K]

Answer:

The camp Purchased 2 small boxes and 4 large boxes.

Step-by-step explanation:

Let Number of Small box purchased be x.

Now Given:

The camp bought 2 more large boxes than small boxes.

Hence Number of large box purchased = x+2

Also Given:

Total Number of Granola bars = 144

Now Each small box has 12 granola bars and each large box has 30 granola bars.

Hence Total Number of Granola bars is equal to sum of number of granola bars in each small box multiplied by number of small box and number of granola bars in each large box multiplied by number of larger box.

Hence equation can be framed as.

12x+30(x+2)=144

Now we will use distributive property to solve the same we get;

12x+30x+30\times2 =144

Now Using multiplication propert we get;

12x+30x+60=144

Now Combining like terms we get;

12x+30x=144-60\\

Now By using Addition and Subtraction property we get;

42x=84

Now Using Division property we get;

\frac{42x}{42}=\frac{84}{42}\\\\x=2

Number of Small boxes purchased = 2

Number of Large boxes purchased = x+2=2+2=4

Hence The camp Purchased 2 small boxes and 4 large boxes.
