Question

Carol sold twice as many magazine subscriptions as Jennifer. If Carol and Jennifer sold 90 subscriptions in all, how many subscriptions did Carol sell?​

Answer 1

60 subscriptions

Explanation:

Let x be the number of subscriptions Jennifer sold.

Carol sold 2x subscriptions.

So, x + 2x = 90

Simplify like terms:

3x = 90

Divide both sides by 3.

`\sf (3x)/(3)=(90)/(3)`

x = 30

Carol sold 2 × 30 = 60 subscriptions.

Therefore, Carol sold 60 subscriptions.

Answer 2

60 subscriptions

Explanation:

We know

Carol sold twice as many magazine subscriptions as Jennifer.

If Carol and Jennifer sold 90 subscriptions in all, how many subscriptions did Carol sell?​

We first have to find the number of subscriptions Jennifer sold. Let's assume the amount of subscriptions sold is x.

We have the equation:

x + 2x = 90

3x = 90

x = 30 subscriptions

So, Jennifer sold 30 subscriptions. Now we substitude 30 in for x and find how many subscriptions Carol sold.

30 x 2 = 60 subscriptions

So, Carol sold 60 subscriptions.
