Question

At a college, the cost of tuition increased by 10%. Let b represent the former cost of tuition. Use the expression b+0.10b for the new cost of tuition.

a. Write an equivalent expression by combining like terms.

b. If the cost increases by 10%, you can multiply the former cost by %.

Answers

  1. The equivalent expression by combining like terms is 1.10b and
    If the cost increases by 10%, you can multiply the former cost by 110%

    How to determine the equivalent expression by combining like terms.

    From the question, we have the following parameters that can be used in our computation:
    Expression of 10% raise = b + 0.10b
    Evaluate the like terms in the above expression
    So, we have the following representation
    Expression of 10% raise = 1.10b

    How to complete the blank

    Here, we have
    If the cost increases by 10%, you can multiply the former cost by %.
    In this case, the factor is calculated as
    factor = 1 + 10%
    So, we have
    Factor = 110%
    So, the missing statement is 110%
