Can I get help with this problem please

Given the following utility function: U = 2X + 2Y and marginal utilities MU, = 2, MU, = 2 A consumer facing the following prices: PX = $10, P. =1 chooses to consume 17 units of good X and 11 units of good Y. Assume that graphically good X is on the horizontal axis and good Y is on the vertical axis. Given this consumption bundle, the marginal rate of substitution is equal to - (Round your answer to two decimal places. Note that the minus sign is already included.). Given this value, the consumer should consume in order to maximize his/her utility
