Part 3 Jason and Victoria work at a Greenly’s Toy Store. Jason sells 15 toys per hour. Victoria sells 15 toys per hour. Victoria sold an additional 22 toys more than Jason. Write an expression that represents the weekly sales for both Jason and Victoria. Use the same variable for both people. Let the variable represent the number of hours worked. (1 pt) *Jason = 15j and Victoria = 15v + 22Jason = 15j and Victoria = 15j + 22Jason = 15/j and Victoria = 22jJason = 15/j and Victoria = 15/v + 22Jason = 15j and Victoria = 15j - 22Jason = j + 15 and Victoria = v + 37This one is multiple choice Charles and Stacy work at a shoe store. They are both paid $9 per hour. This week Charles made an extra $32 in overtime. Which expressions represent the weekly wages for Charles and Stacy. c = the number of hours that Charles worked for the week s = the number of hours that Stacy worked for the week.

You originally draw a design for an art contest on a 3 in. x 5 in. card. The second phase of the contest requires the drawing to be transferred to an 8.5 in x 11 in. standard sheet of paper and utilize as much of the space on the paper as possible. You determine that the largest size one of the dimensions of your drawing can be is 10.5 in. What is the length of the other dimension if the two drawings are similar? Type your exact answer in the blank without the units, and round to the nearest tenths.Is the answer 4.2 or 8.4? or something else entirely

A chemist has 500 ml of a 30% acid solution. She adds x milliliters of a 10% acid solution. Which statement is true about the graph of the function that represents the concentration of the final solution? The horizontal asymptote y = 30 means that the final concentration will always be less than 30%. The horizontal asymptote y = 10 means that the final concentration will always be greater than 10%. The vertical asymptote x = 500 means that the volume of solution will always be greater than 500 ml. The vertical asymptote x = 0 means that the volume of the solution will always be greater than 0.
