Pls on b and c, i will mark u brainliest. pls correct me if i did anything wrong on part a.

A) correct

B) 1500mL × 0.01695 = $25.425

C) 1500mL × 0.0199 = $29.85

Step-by-step explanation:

Problem A looks correct

The least expensive way to buy 1,500mL of the cleaner is the one with the lowest price per mL:

1500mL × 0.01695 = $25.425

The most expensive way is the one with the highest price per mL:

1500mL × 0.0199 = $29.85

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
