X = mary's shells
g = 1 1/4x + 5
n = 1 1/2x+ 1
g = n
1 1/4x + 5 = 1 1/2x + 1
5/4x + 5 = 3/2x + 1...multiply by common denominator of 4, this will get rid of fractions...however, this is optional...u can work with fractions if u wish.
5x + 20 = 6x + 4
5x - 6x = 4 - 20
-x = - 16
x = 16....so Mary has 16 shells
U say the answer is D 7$......
A because the feed sets discounts rate and primes
It is 6.5 days actually. 3.6/0.2= 13. Since it goes by a half of a day, divide the 13 and 0.5. 6.5 should’ve been that students answer.
