Uncle sammy invests money on stocks and makes 7 to 13 percent the range of money uncle sammy will make if he invests his next paycheck of $2,300. express the solution set in set notation and interval notation.

So we are given an increase of 7% to 13%, so we multiply the capital with 1.07 and 1.13. So the range is:

minimum = $2,300 * 1.07 = $2,461

maximum = $2,300 * 1.13 = $2,599

The set notation is:

interest, X = {7%, 13%}

money, Y = {$2461, $2599}

The interval notation is:

[$2461, $2599]

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
