Question

Ally sold 5 oven toasters and 3 rice cookers for $500. If a rice cooker cost $20 less than an oven toaster, find the cost of a rice cooker.

Answer 1

The answer is 50

X represents a toaster, x-20 represents a rice cooker
Use the equation 5x+3(x-20)=500
Solve for x and get 70. 
A toaster is 70 but a rice cooker is 50
