    Who can solve this here

    a. complete the chart for each problem
    b. use the chart to write an equation
    c. solve the equation and answer the question, explain if there is no solution

    At a sandwich shop, sandwiches cost $1.50 each and fruit drinks $.40 each. If a bill for an order of 20 items was $17, how many fruit drinks were ordered.

    Here's the chart

    1.Number of each * 2.Value = 3.Total value
    Fruit drinks: 1. x 2. .40 3.fill in the blank

    Sandwiches: 1. fill in blank 2. 1.50 3.fill in the blank

    You were supposed to have read the guidelines when you registered for the forum! Thus, you should know that no one is going to do your homework for. That wouldn't help you or us. Try the problem your self so we will know what kind of help you need. (As far as I can see, there is no way to simply "write down" the information in the blanks. You will need to set up two equations and then solve the equations simultaneously to find the information you need.)
