Correct answer is C.
m + 3s = 50
the total number of questions is 20. since the paper is made of only multiple choice and short answer questions, the sum of the multiple choice and short answer questions should be 20.
since multiple choice is 'm' and short answer is 's'
then m + s = 20
but theres no option for that
if we take the number of points
points for 1 multiple choice question - 1
then points for m number of multiple choice questions = 1 * m = m
points for 1 short answer - 3
then points for s number of short answer question = 3 * s = 3s
then total number of points = m + 3s
and the total number of points = 50
therefore
m + 3s = 50
this is the correct answer C.
She got back $2.50 hope this helped
41 x 0.15 = 6.15, which means only 6 bands will compete.
Hope this helps.
Bob's Bikes
260 × 0.2 = 52
260 - 52 = 208
208 × 2 = $416.00
Walt's Wheels
300 × 0.6 = 180
300 - 180 = 120
120 × 2 = $240.00
Carson's Cycles
310 × 0.1 = 31
310 - 31 = 279
279 × 2 = $558.00
(i can't read what it says for $50, comment below if it makes a difference, i'll edit)
Tino's Transportation
260 ÷ 2 = 130
260 + 130 = $390.00
B) Walt's Wheels provides the lowest price for two bicycles.
