which is the correct solution set for 4x^2 +4x -3 = 0? (1) {2,-3}(2) {1/2, -3} (3) {1,2}(4) {1/2, -3/2}

He has to pay $ 2.76 for the yogurt.

Step-by-step explanation:

Given data

Cost of each ounce = $ 0.24

Vanilla yogurt = 6.5 ounces

Strawberry yogurt = 5 ounces

Total ounces = 6.5 + 5 = 11.5 ounces

Now Total cost of yogurt = 11.5 × 0.24

Now Total cost of yogurt = $ 2.76

Therefore he has to pay $ 2.76 for the  yogurt.
