The smiths spend 7% of their budget on entertainment. their total budget this year is $2,000 more than last year, and this year they plan to spend $3,290 on entertainment. what was their total budget last year

$45,000

Step-by-step explanation:

In order to find the budget from last year, you can use the information given to first find the budget for this year.  Given that $3,290 represents 7% of this year's budget, you can set up a proportion to find the total budget for this year:

, where 'x' is the amount of the total budget

Cross-multiply and divide:  7x = (3,290)(100) or 7x = 329,000

Solve for x:  x = $47,000

Since $47,000 represents the total budget for this year, which is $2000 more than last year, you can subtract to find last year's budget:

$47,000 - $2,000 = $45,000

i think the answer is b)

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
