Hector and francis spent a total of $47.50 at the mall. if hector spent 50% more than francis, how much did francis spend at
the mall?
o
$19.00
$23.50
$28.50
$31.67

The answer is A ($19)

Step-by-step explanation:

The total amount spent between the two person = $47.5

If Hector is represented by H

Francis represent by F

Therefore equation 1 = H + F = 47.5

H +F = 47.5 (eqn 1)

From the question

Hector = Francis + 50% Francis

Translating this into an equation we get,

H = F + 0.5F (eqn 2)

Substitute equation 2 into equation 1, we get:

(F + 0.5F) + F = 47.5

Thus 2.5F = 47.5

F = 47.5/2.5 = 19

Since Francis spend is represented by F, the amount spent by Francis is therefore $19 as obtained from our calculation.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
