answer

94

set up equations

average = total points / number of tests

total points = test1 + test2 + test3 + test4+ test5

total points = 88 + 94 +89 + 85 + test5

total points = 356 + test5

plug total points into first eqation and rearrange

average = total points / number of tests

average = (356 + test5)/number of tests

average * number of tests = 356 + test5

test5 = average * number of tests - 356

plug in values for average and number of tests

test5 = average * number of tests - 356

test5 = 90 * 5 - 356

test5 = 94

If $120.99 is charged for 654 units of electricity
pochemuha

Answer:

The cost of one unit of electricity is $0.185

Step-by-step explanation:

Amount charged = $120.99

Units of electricity used = 654

The cost of a unit of electricity can be determined by dividing the amount charged by the number of units used.

So that,

cost of one unit of electricity = \frac{120.99}{654}

                                    = 0.185

cost of one unit of electricity = $0.185

This implies that the cost of electricity used is charged at $0.185 per unit.

Thus for 654 units of electricity used, the cost would be;

654 x $0.185 = $120.99
