Suzie is making granola. she uses almonds,walnuts, and pecans in the ratio of 4:2:5. lilly uses 50 ounces of walnuts. (
patriot [66]
The weight of the almonds would be 100 ounces and the total weight of the granola would be 275 ounces since 50 / 2 = 25 to find out what to multiply the other ones by so you do 4 x 25 = 100 then 5 x 25 = 125 finally add all of it together 125 + 100 + 50 = 275 ounces.

You are choosing between two health clubs. Club A offers membership for a fee of $ 28$28 plus a monthly fee of $ 20.$20. Club B
eimsori [14]

Answer:

That is to say that at 3 months, the values of the club are equal.

Club A = 268 dollars in total

Club B = 295 dollars in total

Step-by-step explanation:

The first thing is to propose an equation for each club. Let m be the number of months.

Club A = 28 + 20 * m

Club B = 19 + 23 * m

Now, to know when it is the same, we must equal the value of Club A with Club B, it would look like this

28 + 20 * m = 19 + 23 * m

By rearranging the equation we have:

23 * m - 20 * m = 28-19

3 * m = 9

m = 3

That is to say that at 3 months, the values of the club are equal.

Now to know the total value, we will do it with an annual membership, which would be a total of 12 months, therefore it is to replace in the equation of each one:

Club A = 28 + 20 * 12 = 268 dollars in total

Club B = 19 + 23 * 12 = 295 dollars in total
