Q. A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly and at a constant rate. After 88 months, he weighed 138138 kilograms. He started at 9090 kilograms.Let yy represent the sumo wrestler's weight (in kilograms) after xx months.\newlineComplete the equation for the relationship between the weight and number of months.\newliney=y=\square
  1. Determine rate of weight gain: Determine the rate of weight gain per month.\newlineThe sumo wrestler started at 9090 kilograms and weighed 138138 kilograms after 88 months. To find the rate of weight gain per month, we subtract the starting weight from the weight after 88 months and divide by the number of months.\newlineRate of weight gain per month = (Weight after 88 months - Starting weight) / Number of months\newlineRate of weight gain per month = (138kg90kg)/8months(138 \, \text{kg} - 90 \, \text{kg}) / 8 \, \text{months}\newlineRate of weight gain per month = 48kg/8months48 \, \text{kg} / 8 \, \text{months}\newlineRate of weight gain per month = 6kg/month6 \, \text{kg/month}
  2. Calculate weight after x months: Write the equation for the sumo wrestler's weight after x months.\newlineWe know that the wrestler gains 66 kilograms each month. Therefore, the weight after xx months can be calculated by starting with the initial weight and adding 66 kilograms for each month that passes.\newliney=Initial weight+(Rate of weight gain per monthNumber of months)y = \text{Initial weight} + (\text{Rate of weight gain per month} * \text{Number of months})\newliney=90kg+(6kg/monthx)y = 90 \, \text{kg} + (6 \, \text{kg/month} * x)
  3. Simplify the equation: Simplify the equation.\newlineThe equation from Step 22 is already in its simplest form, so no further simplification is needed.\newliney=90+6xy = 90 + 6x
