1. The cost of attending college has been rising at an average increase of 7% for the past ten years. How much will a college that now costs $10,368 for room, board, tuition and fees cost

two years from now?

$11,870.32

Step-by-step explanation:

Use a compound interest formula for this as it shows what happens when when something increases at a certain rate per period.

= Amount * (  1 + rate) ^ no. of periods

= 10,368 * ( 1 + 7%) ²

= 10,368 * 1.1449

= $11,870.3232

= $11,870.32

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

answer: get a conversion sheet out i dont know the exact measurments

step-by-step explanation: divide the number of feet with the nu,ber of milrs and there your answer
