Your brother is correct, because the sequence is increasing.
Answer:
x 45
___ = ____ (solve for x) = 39.6
88 100
88 + 39.6 = £127.60, was the original price.
Answer: n = -198
Step-by-step explanation: To find n we need to work backwards, so we need to multiply -11 x 18 to get -198. So n would be -198.
To make this easier, you want to do 5 1/2 into a decimal. 5.5, next divide to find her pace per minute. 12/ 5.5 =2.1818
Multiply that by 60, and your answer is 130
12 for $25 is $2.08 per each. 24 for $46 is $1.90 per each. 50 for $94 is $1.90 per each.
