The rate of change in this pattern is 2:1 comparing the change in 'y' to the change in 'x'.. this means that if you go form 33 to 51 ( an increase of 18), then the the increase from 16 to ? will be 9. Therefore, ? = 16 + 9 or 25
? = 25
y-intercept of the line would be 14 in that case.
SO, YOUR ANSWER IS 14
Answer:
a = $17.25
Step-by-step explanation:
let the money spend on the necklace be a
we have
15.75 +1.5*2 +a + 14 = 50
-> a = 50 -15.75 -3-14
-> a = $17.25
Change you’ll receive is = 0.09
you can only buy 11 because if you divide 20/11 it will give you 1.81 and if you multiply 11x 1.81 it will give you 19.91 which is close to $20 & that’s the most you can buy .
