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

there are 4our
Answer:
The 2nd case is the better value
Step-by-step explanation:
£11.45
Case 1: That would be £11.45 + -------------- for the two shirts. This comes
2
out to 1.5(£11.45) = £17.175 for two shirts.
Case 2: Two shirts for £10.16 each comes out to £20.32; multiplying that by (1.00 - 0.20), or (0.80) results in (0.80)(£20.32) = £16.256.
The 2nd case is the better value, as one would get 2 shirts for £16.26, versus 2 shirts for £17.18 in the other case.
