Answer:

The expressions for the payment made to Mary are,

(Monday) 90 = 15m + b

(Tuesday) 62 = 8m + b

where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.

The equation that represents Mary's earning is

y = 4x + 30

For 20 students,

y = 4(20) + 30 = 110

For Lisa's earnings,

y = 8x + 15

Substituting 20,

y =8(20) + 15 = 175

Thus, Lisa would earn more than Mary by $65.

(Btw this is not my work, I got it from someone else on brainly and wanted to help lol)

The height of a triangle is twice its base. If its area is 121cm^2 Find its base​
kozerog [31]

Answer:

The base is 11 cm.

Step-by-step explanation:

The formula for the area of a triangle is A = \frac{1}{2} bh. If we plug in what we know to this equation, we are left with 121 = \frac{1}{2} * b * 2b, which we now need to simplify.

First, we combine like terms.

121 = \frac{1}{2} * 2b^{2}

Then, we can eliminate the \frac{1}{2} and 2 on the right side of the equation, since they cancel each other out.

121 = b^{2}

Finally, we take the square root of both sides of the equation and find our answer:

11 = b

The original price of a jacket was 72.50$ Maria used a coupon for 20% off to buy the jacket. How much did she pay before tax?
Afina-wow [57]

Answer: Maria payed $58.00 for her jacket BEFORE tax.

Step-by-step explanation:

To find the answer to this question, we must first multiply 72.50 by 0.20. After doing so, we get 14.5 (this is the sale money). Finally, we subtract $72.50-14.5 to get out answer, 58 dollars.
