Jim and Abby each bought burgers and fries from the concession stand at the fair. Jim bought 3 burgers and 2 orders of fries for $17. Abby bought 2 burgers and 4 orders of fries for $18. Based on the information above, how much did the concession
stand charge for each burger?

How much did it charge for each order of fries?

HINT:
b = price for a burger
f = price for french fries
Jim bought 3 burgers and 2 orders of fries for $17.

B = price for a burger
F= price for fries

Jim equals 3b + 2f = $17

Abby equals 2b + 4f = $18

Multiply the first equation by -2 & use the elimination to solve

I need would really appreciate if whomever helps me to show the steps. Thank you.

Ascientist studied a population of workers to determine whether verbal praise and/or tangible rewards affect employee productivity. in the study, some workers were offered verbal praise, some were offered tangible rewards (gift cards, presents, and some were offered neither. the productivity of each participant was measured throughout the study by recording the number of daily tasks completed by each employee. which inference might the scientists make based on the given information? a.) the number of daily tasks completed by each employee may influence the dependent variable, which is whether the employee receives verbal praise, tangible rewards, or neither. b.) verbal praise and/or tangible rewards may influence the independent variable, which is the number of daily tasks completed by each employee. c.) verbal praise and/or tangible rewards may influence the dependent variable, which is the number of daily tasks completed by each employee. d.) the dependent variables, which are verbal praise and tangible rewards, may influence the number of daily tasks completed by each employee.
