Answer:
409.86
Step-by-step explanation:
230×.65=149.50
230+149.50=379.50×.08=30.36
379.50+30.36=409.86
Answer:
Gradient of line A = 4
Gradient of line B = -2
Step-by-step explanation:
To solve this question, we will use the formula for gradient passing through two points 
and 
,
Gradient (m) = 
For line A,
Since, line A passes through (3, 6) and (4, 10)
Gradient of line A = 
= 4
For line B,
Since, line B passes through (1, 6) and (2, 4),
Gradient of line B = 
= -2
Answer:
$22.40
Step-by-step explanation:
For this question you have to use decimal multipliers to work out the sale price of the cola given the information that in a grocery store, a $32 case of soda is labelled get a 30 % discount so to use decimal multipliers we have minus 100 by 30 and then divide by 100
→ We have to minus 100 by 30
⇒ 70
→ And then divide by 100
⇒ 70 ÷ 100 = 0.7
0.7 is the decimal multiplier for this question so we multiply it by the case of soda price with is $32 so
32 × 0.7 = 22.4
The sale price of the case of soda is $22.40 considering a 30% discount on a $32 case of soda
60/2 weeks = 30/week
70 days * 7 days/week = 10 weeks
10 weeks * 30/week = $300
They will save $300 in 10 weeks
