Answer: 104$
Explanation:
She is paid 7$ for each of the first 7 demo
And she is paid 11$ for each demo over the 7 demo
But she did 12 demo, which mean the first 7 demo she got paid 7$ each and for the last 5 demo she got paid 11$ for each demo.
(7 • 7) + (11 • 5)
= 49 + 55
= 104$
Answer:62% increase
Step-by-step explanation:
old price of cereal box = 18.5 ounces
New price of cereal box =30 ounces
Percent change = (New Price - old price / Old price ) x 100
30 - 18.5 / 18.5 x 100
11.5/18.5 x100
0.621 x100
= 62% increase
For the second question, the answer would be A because the lines intersect at 2 and -1.4. For the first question, t+b is less than or equal to 20 and 15b+8b is greater than or equal to 150 is the answer because Nick can work <u>up to </u>20 hours and needs to make <u>at least</u> $150 per week so that answer fits best. That question is solved mostly by context clues.
Answer: B.
18 + 46 = 60
A. 3(6+14) = 48

I’m happy to help :) !
Answer:
f(a+h) = 2(a+h)³ = 2a³+6a²b+6ab²+2b³
Step-by-step explanation:
f(x) = 2x³
f(a+h) = 2(a+h)³
The question is not clear on how the answer should be presented.. but if you need to expand and simplify.......then:
f(a+h)
= 2(a³+3a²b+3ab²+b³)
= 2a³+6a²b+6ab²+2b³
