Q. Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.Eli gets paid at home for doing extra chores. Last week, he did 8 loads of laundry and 3 loads of dishes, and his parents paid him $35. The week before, he finished 8 loads of laundry and 6 loads of dishes, earning a total of $38. How much does Eli earn for completing each type of chore?Eli earns $_____ per load of laundry and $_____ per load of dishes.
Define Variables: Let's denote the price per load of laundry as l and the price per load of dishes as d. Eli's earnings for 8 loads of laundry and 3 loads of dishes are $35, leading to the equation 8l+3d=35.
Set Up Equations: From the previous week, Eli did 8 loads of laundry and 6 loads of dishes for $38, giving us the equation 8l+6d=38.
Eliminate Variable: To eliminate one variable, we'll focus on eliminating l. Multiply the first equation by −1 to align the coefficients of l for subtraction. −8l−3d=−35.
Solve for d: Add this equation to the second equation: −8l−3d+8l+6d=−35+38, simplifying to 3d=3.
Substitute and Simplify: Solve for d: d=33, which simplifies to d=1.
Solve for l: Substitute d=1 back into the first equation: 8l+3(1)=35. Simplify to 8l+3=35.
Solve for l: Substitute d=1 back into the first equation: 8l+3(1)=35. Simplify to 8l+3=35. Solve for l: 8l=35−3, which simplifies to 8l=32. Then, l=832, which simplifies to l=4.
