This is like math.. 28 divided by 4 = 7.. 7 x 30 = 210 so your answer is 210.

You need to make a proportion

beats         28     x
seconds     4       30


cross multiply and divide

(28) (30) = 4x

840 = 4x
210 = x

Pls help with this math problem
sukhopar [10]

Answer:

y = 1500 - 63x. See the attached for a graph.

Step-by-step explanation:

Each withdrawal will total $63, which includes $60 cash and a $3 fee. Then x withdrawals will total 63x dollars. This amount is subtracted from the initial account balance of 1500 to give the amount remaining.

If y represents the account balance, the equation can be written as

... y = 1500 -63x

The graph will have a y-intercept of 1500, and a slope of -63.
