Are there options for this
Hi
3 dinners at $9 each.
9 x 3
2 kids' meals at $4 each
9 x 3 + 4 x 2
4 desserts at $3 each
9 x 3 + 4 x 2 + 4 x 3
$10 dollar off coupon
9 x 3 + 4 x 2 + 4 x 3 - 10
Solve using PEMDAS
9 x 3 + 4 x 2 + 4 x 3 - 10 = ?
27 + 8 + 12 - 10 = ?
35 + 12 - 10 = ?
47 - 10 = ?
37
The answer is 37
Hope this helps! :)
Answer:
$2,221.6 monthly
Step-by-step explanation:
A = P(1 + r)^n
A is the total amount I intend to save = $15,000
r is the yearly interest rate = 3.6% = 0.036
n is the duration to achieve my goal = 4 and 1/2 years = 54 months
15,000 = P(1 + 0.036)^54
15,000 = P(1.036)^54
P = 15,000/6.752 = 2,221.6
I need to put $2,221.6 into the savings account monthly
Option D I believe because it is the only one that passes the vertical line test (the test that for every X value, there is only 1 Y value).
Working alone Joan finish the job in 60 minutes, which means every minute she does 1/60 of the whole job.
suppose the sister can finish the job alone in x minutes, every minute she does 1/x of the whole job.
together they do (1/60 +1/x) part of the job every minute.
for 40 minutes they finish the whole job: (1/60 +1/x)*40=1 (1 represents the whole job)
40/60 +40/x =60/60
40/x=20/60
x=120
so it will take the sister 2 hours to finish the job alone
