Answer:
7
Step-by-step explanation:
ab - cd = ?
Put the numbers into the correct variables of the equation.
(5)(3) - (4)(2) = ?
Now multiply 5 and 3 with each other. This leaves you with:
15 - (4)(2) = ?
Now, multiply 4 and 2 with each other. This leaves you with:
15 - 8 = ?
Now, you are able to solve the equation.
15 - 8 = 7
Answer:
$8.50
Step-by-step explanation:
Multiply the cost by the amount of candy she bought, your equation will look like this:
2(0.75) + 3(1) + 5(1.40)
Multiplying everything makes the equation into:
1.5 + 3 + 7
Adding everything makes the total cost 11.50.
Subtract 11.50 from 20, and the answer is 8.50
