Fiona and her friends went to a smoothie shop. they ordered three strawberry smoothies and two protein shakes for a total of $24.00. last week they ordered one strawberry smoothie and four protein shakes for a total of $25.50. the system that represents their purchases is below. x 4y = 25.50 3x 2y = 24.00 what is the price of a protein shake? $3.75 $4.50 $4.95 $5.25

The answer is: The value of the protein shake is: $ 5.25.

Step-by-step explanation:

x + 4y = 25.50 3x + 2y = 24.00, the steps to follow to solve this equation would be: a) clear x of the first, and it would be: x = 25.50 - 4y; b) now we substitute it in the second equation, and it would be as follows: 3 (25.30 - 4y) + 2y = 24.00; 76.50-12y + 2y = 24.00; 76.50 - 24.00 = 10y; y = 5.25; c) we calculate the value of x = 25.50 - 4 (5.25); 35.50 - 21 = 4.50 = x. Where the value of the protein shake is: $ 5.25.

The answer is: The value of the protein shake is: $ 5.25.

step-by-step explanation:

35x4=140

140/20=7

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
