(d) Using the equation y=10x+200 find the value of x when y is 250. Then, choose the best description of this value of x. x=square Description: The amount (in dollars)in the account after 5 years The number of years it takes for the amount in the account to reach 200 The number of years it takes for the amount in the account to reach 250

To find the value of x when y is 250, we can substitute y = 250 into the equation and solve for x.<br /><br />$y = 10x + 200$<br /><br />$250 = 10x + 200$<br /><br />Subtract 200 from both sides:<br /><br />$50 = 10x$<br /><br />Divide both sides by 10:<br /><br />$x = 5$<br /><br />So, the value of x when y is 250 is 5.<br /><br />The best description of this value of x is: The number of years it takes for the amount in the account to reach $250.
